</li> Fixed a problem that may cause an access violation when you are using the Microsoft JDBC/ODBC Bridge to open and close many database connections from multiple threads.</li> Fixed a problem in the AWT text components in which the SHIFT+BACKSPACE key combination moves the cursor position but does not delete the previous character.For additional information, click the article number below to view the article in the Microsoft Knowledge Base:

260053 FIX: SHIFT+BACKSPACE Breaks Cursor Position in an AWT TextField

</li> Fixed a problem on Windows NT 4 Terminal Server Edition in which the system property com.ms.windir is incorrectly set to a user-specific folder under the current user's profile instead of the true Windows folder.</li> Fixed a problem in which the reading of data from a java/net/SocketInputStream causes a memory leak if the buffer is greater than 20,000 bytes, if the socket has a SO_TIMEOUT value set, and if the read operation fails because of an actual timeout or other socket failure.</li> Fixed a memory leak that arises when java/applet/AudioClip.play is used.For additional information, click the article number below to view the article in the Microsoft Knowledge Base:

261061 FIX: System Handles Created Via AudioClip.play Are Not Being Freed

</li> Fixed a problem in which the byte-to-character converters for Big5, GB2312, and KSC5601 (used for Korean and Chinese) are incorrectly ignoring null-bytes. These converters now correctly convert zero bytes into a zero Unicode character.For additional information, click the article number below to view the article in the Microsoft Knowledge Base:

260823 FIX: Some Character Encoders Ignore Null Bytes

</li> Corrected a regression in the 32xx series of the Microsoft VM in which the following character converter aliases are missing: iso-2022-jp, csiso2022jp, jis_encoding, and csjisencoding.

</li> <li>Fixed a problem in which the Microsoft VM may cause an access violation instead of throwing an StackOverflowError exception when the call stack is exhausted.</li> <li>Fixed a problem in which an applet that is run from the root folder of a local drive is incorrectly unable to access files in that folder.</li> <li>Fixed a problem in which an exception is thrown if a java/awt/PrintJob is used, and if the user chooses to print to a file but then cancelled when prompted for a file name.For additional information, click the article number below to view the article in the Microsoft Knowledge Base:

261100 FIX: Unexpected Exceptions Thrown During Printing

</li> <li>Fixed a problem with the implementation of the IDispatch interface that the Microsoft VM automatically exposes for Java objects. Under some circumstances, this issue causes the IDispatch::GetIdsOfNames method to return the wrong DISPID for class members with names that are longer than 15 characters.</li> <li>Fixed a problem in which poorly written ClassLoaders are allowed to load a given class multiple times. This causes corruption of the Microsoft VM's internal data structures and typically results in an access violation. The Microsoft VM now prevents a ClassLoader instance from defining a given class more than once.For additional information, click the article number below to view the article in the Microsoft Knowledge Base:
