&xslt4j; 2.0.D07 incorporates a Xalan-Java 1 compatibility jar, some performance enhancements, and a number of bug fixes for bugs found in version 2.0.D06.

Compatibility jar: xalanj1compat.jar

This release includes a new JAR in the bin directory --xalanj1compat.jar, that lets you rebuild your Xalan-Java 1.x applications to run with Xalan-Java 2. As a point of reference, this JAR includes the API required to recompile the Xalan-Java 1.x core sample applications (excluding the sample extensions) and run them with Xalan-Java 2. To use this compatibility layer with an existing Xalan-Java 1.x application, do the following:

1. Place xalanj1compat.jar on the system classpath in front of the Xalan-Java 2 xalan.jar (both are in the bin directory).
   
   
2. Recompile your application. It it does not compile, you may be using Xalan-Java 1.x API that the compatibility layer does not support.
   
   
3. Run the recompiled application with xalanj1compat.jar on the system classpath in front of the Xalan-Java 2 xalan.jar.

We want our Xalan-Java 1.x users to start using Xalan-Java 2. That is where we are concentrating our efforts to improve performance and fix any outstanding bugs. To see what portion of the Xalan-Java 1.x API we have included in xalanj1compat.jar, see Xalan-Java 1 compatibility Javadoc. For example, the compatibility layer does not support the use of Xalan-Java 1.x extensions. If you feel that we should extend our compatibility JAR to support additional Xalan-Java 1.x API calls, please let us know exactly what you would like to see.

Other changes

Along with performance enhancements, we have fixed a number of bugs found in Xalan-Java 2.0.D06:

• Fixed handling of disable-output-escaping="no". Previously, once it was turned on, it could not be turned off.
  
  
• Fixed a bug with whitespace handling where Xalan was incorrectly checking for whitespace stripping before collation of multiple whitespace events into a single text node.
  
  
• Whitespace stripping wasn't working with input DOMs before. This is now fixed.
  
  
• Fixed many exception handling problems and problems with error reporting.
  
  
• Fixed a bug resetting parameters in Transformer clearParameters().
  
  
• Fixed a bug where CDATA sections were not matching the text() node test.
  
  
• Made better memory allocation problem with result tree fragments.
  
  
• Made result tree fragment parsing of numbers consistent with strings.
  
  
• Exceptions thrown from extensions should now be properly reported via the error listener.
  
  
• Fixed hard-coded stack dump set off by m_reportInPostExceptionFromThread variable.
  
  
• Fixed intermittent threading problem with text nodes being dropped.
  
  
• Fixed problem with variable evaluation inside of union expressions.
