Reusing stylesheet more that 2 times raises exceptions

[Frank E. Weiss]

This problem came from using Ant's Style task after I upgrading an existing Ant 
project to use Xalan-J-2.2.0 after using
2.0.1. I isolated the problem by modifying the trax examples code (code 
appended). The exceptions are sensitive to the
order and number of input documents that are trying to be transformed with a 
stylesheet reuse. Also, the stylesheet
imports other stylesheets.

I'm new to this list, but I did scan the bug reports for similar problems. 
Anybody have suggestions as to how to solve
this problem?

Here are the exceptions that are encountered in the "community" test case:

EXCEPTION:
javax.xml.transform.TransformerException: 
java.lang.ArrayIndexOutOfBoundsException
        at 
org.apache.xalan.transformer.TransformerImpl.transformToRTF(TransformerImpl.java:1741)
...
---------
java.lang.ArrayIndexOutOfBoundsException
        at 
org.apache.xalan.transformer.ResultTreeHandler.flushElem(ResultTreeHandler.java:868)
...
---------
java.lang.ArrayIndexOutOfBoundsException
        at 
org.apache.xml.utils.SuballocatedIntVector.elementAt(SuballocatedIntVector.java:453)


Here's the modified Trax Examples source code:
==========================
 public static void exampleTransformerReuse(Vector sources, String xslID)
 throws TransformerException, TransformerConfigurationException
 {
  TransformerFactory tfactory = TransformerFactory.newInstance();
  Transformer transformer = tfactory.newTransformer(new StreamSource(baseDir + 
xslID));
  for (Enumeration e=sources.elements(); e.hasMoreElements(); )
  {
   String sourceID = (String)e.nextElement();
   System.out.println("\n=========" + sourceID + "\n");
   transformer.transform( new StreamSource(baseDir + sourceID),
           new StreamResult(destDir + sourceID));

  }
 }
