IllegalStateException

java.lang.IllegalStateException

IllegalStateException is described in the javadoc comments as:

Signals that a method has been invoked at an illegal or inappropriate time. In other words, the Java environment or Java application is not in an appropriate state for the requested operation.
author: Jonni Kanerva version: 1.15, 12/19/03 since: JDK1.1

com.sun.org.apache.xerces.internal.jaxp.datatype.DurationImpl.add(Duration)

/**
     * Computes a new duration whose value is <code>this+rhs</code>.
     * For example,
     * '1 day' + '-3 days' = '-2 days'
     * '1 year' + '1 day' = '1 year and 1 day'
     * '-(1 hour,50 minutes)' + '-20 minutes' = '-(1 hours,70 minutes)'
     * '15 hours' + '-3 days' = '-(2 days,9 hours)'
     * '1 year' + '-1 day' = IllegalStateException
     * 
     * Since there's no way to meaningfully subtract 1 day from 1 month,
     * there are cases where the operation fails in
     * {@link IllegalStateException}. 
     * 
     * Formally, the computation is defined as follows.
     * Firstly, we can assume that two {@link Duration}s to be added
     * are both positive without losing generality (i.e.,
     * <code>(-X)+Y=Y-X</code>, <code>X+(-Y)=X-Y</code>,
     * <code>(-X)+(-Y)=-(X+Y)</code>)
     * 
     * Addition of two positive {@link Duration}s are simply defined as  
     * field by field addition where missing fields are treated as 0.
     * A field of the resulting {@link Duration} will be unset if and
     * only if respective fields of two input {@link Duration}s are unset. 
     * Note that <code>lhs.add(rhs)</code> will be always successful if
     * <code>lhs.signum()*rhs.signum()!=-1</code> or both of them are
     * normalized.
     * @param rhs <code>Duration</code> to add to this <code>Duration</code>
     * @return
     *      non-null valid Duration object.
     * @throws NullPointerException
     *      If the rhs parameter is null.
     * @throws IllegalStateException
     *      If two durations cannot be meaningfully added. For
     *      example, adding negative one day to one month causes
     *      this exception.

com.sun.org.apache.xerces.internal.jaxp.datatype.DurationImpl.multiply(BigDecimal)

/**
     * Computes a new duration whose value is <code>factor</code> times
     * longer than the value of this duration.
     * 
     * For example,
     * 'P1M' (1 month) * '12' = 'P12M' (12 months)
     * 'PT1M' (1 min) * '0.3' = 'PT18S' (18 seconds)
     * 'P1M' (1 month) * '1.5' = IllegalStateException
     *  
     * Since the {@link Duration} class is immutable, this method
     * doesn't change the value of this object. It simply computes
     * a new Duration object and returns it.
     * 
     * The operation will be performed field by field with the precision
     * of {@link BigDecimal}. Since all the fields except seconds are
     * restricted to hold integers,
     * any fraction produced by the computation will be
     * carried down toward the next lower unit. For example,
     * if you multiply 'P1D' (1 day) with '0.5', then it will be 0.5 day,
     * which will be carried down to 'PT12H' (12 hours).
     * When fractions of month cannot be meaningfully carried down
     * to days, or year to months, this will cause an
     * {@link IllegalStateException} to be thrown. 
     * For example if you multiple one month by 0.5.
     * 
     * To avoid {@link IllegalStateException}, use
     * the {@link #normalizeWith(Calendar)} method to remove the years
     * and months fields.
     * @param factor to multiply by
     * @return
     *      returns a non-null valid {@link Duration} object
     * @throws IllegalStateException if operation produces fraction in 
     * the months field.
     * @throws NullPointerException if the <code>factor</code> parameter is 
     * <code>null</code>.

java.util.regex.Matcher.appendReplacement(StringBuffer, String)

/**
     * Implements a non-terminal append-and-replace step.
     *  This method performs the following actions: 
     * <ol>
     *   <li> It reads characters from the input sequence, starting at the
     *   append position, and appends them to the given string buffer.  It
     *   stops after reading the last character preceding the previous match,
     *   that is, the character at index {@link
     *   #start()} <tt>-</tt> <tt>1</tt>.  </li>
     *   <li> It appends the given replacement string to the string buffer.
     *   </li>
     *   <li> It sets the append position of this matcher to the index of
     *   the last character matched, plus one, that is, to {@link #end()}.
     *   </li>
     * </ol>
     *  The replacement string may contain references to subsequences
     * captured during the previous match: Each occurrence of
     * <tt>$</tt><i>g</i><tt></tt> will be replaced by the result of
     * evaluating {@link #group(int) group}<tt>(</tt><i>g</i><tt>)</tt>. 
     * The first number after the <tt>$</tt> is always treated as part of
     * the group reference. Subsequent numbers are incorporated into g if
     * they would form a legal group reference. Only the numerals '0'
     * through '9' are considered as potential components of the group
     * reference. If the second group matched the string <tt>'foo'</tt>, for
     * example, then passing the replacement string <tt>'$2bar'</tt> would
     * cause <tt>'foobar'</tt> to be appended to the string buffer. A dollar
     * sign (<tt>$</tt>) may be included as a literal in the replacement
     * string by preceding it with a backslash (<tt>\$</tt>).
     *  Note that backslashes (<tt>\</tt>) and dollar signs (<tt>$</tt>) in
     * the replacement string may cause the results to be different than if it
     * were being treated as a literal replacement string. Dollar signs may be
     * treated as references to captured subsequences as described above, and
     * backslashes are used to escape literal characters in the replacement
     * string.
     *  This method is intended to be used in a loop together with the
     * {@link #appendTail appendTail} and {@link #find find} methods.  The
     * following code, for example, writes <tt>one dog two dogs in the
     * yard</tt> to the standard-output stream:

javax.management.remote.rmi.RMIConnectorServer.start()

/**
     * Activates the connector server, that is starts listening for
     * client connections.  Calling this method when the connector
     * server is already active has no effect.  Calling this method
     * when the connector server has been stopped will generate an
     * <code>IOException</code>.
     * The behaviour of this method when called for the first time
     * depends on the parameters that were supplied at construction,
     * as described below.
     * First, an object of a subclass of {@link RMIServerImpl} is
     * required, to export the connector server through RMI:
     * <ul>
     * <li>If an <code>RMIServerImpl</code> was supplied to the
     * constructor, it is used.
     * <li>Otherwise, if the protocol part of the
     * <code>JMXServiceURL</code> supplied to the constructor was
     * <code>iiop</code>, an object of type {@link RMIIIOPServerImpl}
     * is created.
     * <li>Otherwise, if the <code>JMXServiceURL</code>
     * was null, or its protocol part was <code>rmi</code>, an object
     * of type {@link RMIJRMPServerImpl} is created.
     * <li>Otherwise, the implementation can create an
     * implementation-specific {@link RMIServerImpl} or it can throw
     * {@link MalformedURLException}.
     * </ul>
     * If the given address includes a JNDI directory URL as
     * specified in the package documentation for {@link
     * javax.management.remote.rmi}, then this
     * <code>RMIConnectorServer</code> will bootstrap by binding the
     * <code>RMIServerImpl</code> to the given address.
     * If the URL path part of the <code>JMXServiceURL</code> was
     * empty or a single slash (<code>/</code>), then the RMI object
     * will not be bound to a directory.  Instead, a reference to it
     * will be encoded in the URL path of the RMIConnectorServer
     * address (returned by {@link #getAddress()}).  The encodings for
     * <code>rmi</code> and <code>iiop</code> are described in the
     * package documentation for {@link
     * javax.management.remote.rmi}.
     * The behavior when the URL path is neither empty nor a JNDI
     * directory URL, or when the protocol is neither <code>rmi</code>
     * nor <code>iiop</code>, is implementation defined, and may
     * include throwing {@link MalformedURLException} when the
     * connector server is created or when it is started.
     * @exception IllegalStateException if the connector server has
     * not been attached to an MBean server.
     * @exception IOException if the connector server cannot be
     * started.

javax.imageio.IIOParam.setSourceSubsampling(int, int, int, int)

/**
     * Specifies a decimation subsampling to apply on I/O.  The
     * <code>sourceXSubsampling</code> and
     * <code>sourceYSubsampling</code> parameters specify the
     * subsampling period (<i>i.e.</i>, the number of rows and columns
     * to advance after every source pixel).  Specifically, a period of
     * 1 will use every row or column; a period of 2 will use every
     * other row or column.  The <code>subsamplingXOffset</code> and
     * <code>subsamplingYOffset</code> parameters specify an offset
     * from the region (or image) origin for the first subsampled pixel.
     * Adjusting the origin of the subsample grid is useful for avoiding
     * seams when subsampling a very large source image into destination
     * regions that will be assembled into a complete subsampled image.
     * Most users will want to simply leave these parameters at 0.
     *  The number of pixels and scanlines to be used are calculated
     * as follows.
     * The number of subsampled pixels in a scanline is given by
     * <code>truncate[(width - subsamplingXOffset + sourceXSubsampling - 1)
     * / sourceXSubsampling]</code>.
     * If the region is such that this width is zero, an 
     * <code>IllegalStateException</code> is thrown.
     * The number of scanlines to be used can be computed similarly.
     * The ability to set the subsampling grid to start somewhere
     * other than the source region origin is useful if the 
     * region is being used to create subsampled tiles of a large image, 
     * where the tile width and height are not multiples of the 
     * subsampling periods.  If the subsampling grid does not remain
     * consistent from tile to tile, there will be artifacts at the tile
     * boundaries.  By adjusting the subsampling grid offset for each
     * tile to compensate, these artifacts can be avoided.  The tradeoff
     * is that in order to avoid these artifacts, the tiles are not all
     * the same size.  The grid offset to use in this case is given by:
     * grid offset = [period - (region offset modulo period)] modulo period)
     *  If either <code>sourceXSubsampling</code> or
     * <code>sourceYSubsampling</code> is 0 or negative, an
     * <code>IllegalArgumentException</code> will be thrown.
     *  If either <code>subsamplingXOffset</code> or
     * <code>subsamplingYOffset</code> is negative or greater than or
     * equal to the corresponding period, an 
     * <code>IllegalArgumentException</code> will be thrown.
     *  There is no <code>unsetSourceSubsampling</code> method;
     * simply call <code>setSourceSubsampling(1, 1, 0, 0)</code> to
     * restore default values.
     * @param sourceXSubsampling the number of columns to advance
     * between pixels.
     * @param sourceYSubsampling the number of rows to advance between
     * pixels.
     * @param subsamplingXOffset the horizontal offset of the first subsample
     * within the region, or within the image if no region is set.
     * @param subsamplingYOffset the horizontal offset of the first subsample
     * within the region, or within the image if no region is set.
     * @exception IllegalArgumentException if either period is
     * negative or 0, or if either grid offset is negative or greater than
     * the corresponding period.
     * @exception IllegalStateException if the source region is such that
     * the subsampled output would contain no pixels.

Recovering WebLogic Passwords

In one of my previous articles ( here ) I explained that the SerializedSystemIni.dat file in WebLogic contains the key used to encrypt and decrypt passwords. If you're not currently keeping this file secure I suggest you do, as with it someone can (to name a few things): Decrypt the WebLogic admin username and password from boot.properties. Recover database passwords, if JDBC Connection pools are configured, from config.xml. Recover the keystore passwords from config.xml and obtain SSL certificates stored in the jks keystores. Essentially, they can do whatever they want, so if you don't know who can read your SerializedSystemIni.dat files, look... now. In this article I will show how easy it is for this file to be used to recover lost passwords via a simple WLST script. The Script The script I use to decrypt passwords is incredibly short, and it works with WebLogic 8, 9 and 10 (probably for version 7 too). To use it, just create a new file called decryptpwd.py and paste the fol
