xalan-doc-cache-off => ArrayIndexOutOfBoundsException

[Christian Brandenstein]

Hi all,
I'm using the <?xalan-doc-cache-off?> PI in the <xsl:for-each> element:
 <xsl:template name="lookup-module">
    <xsl:for-each select="document(@id)/module/*[not(self::meta)]">
      <?xalan-doc-cache-off?>
      <xsl:copy-of select="."/>
   </xsl:for-each>
 </xsl:template>
This works fine for the first call to "lookup-module", but for the 
second call I get the following stack:

java.lang.RuntimeException: java.lang.ArrayIndexOutOfBoundsException

Exception in thread "main"

Xalan catches some Exception in TransformerImpl and throws the 
RuntimeException there. Guess the original Exception came from that code 
part in org.apache.xpath.SourceTreeManager:

 /** JJK: Support  <?xalan:doc_cache_off?> kluge in ElemForEach.
  * TODO: This function is highly dangerous. Cache management must be 
improved.
  *
  * @param n The node to remove.
  */
 public void removeDocumentFromCache(int n)
 {
   if(DTM.NULL ==n)
     return;
   for(int i=m_sourceTree.size()-1;i>=0;--i)
   {
     SourceTree st=(SourceTree)m_sourceTree.elementAt(i);
     if(st!=null && st.m_root==n)
     {
   m_sourceTree.removeElementAt(i);
   return;
     }
   }
 }

However, when I invoce my stylesheets with the 
org.apache.xalan.xslt.Process processor, the error doesn't occur. It 
only occurs when I use my own wrapper, which uses TransformerHandler 
classes set up with Templates stylesheets. In the URIResolver I return a 
DOMSource to the processor.

Any ideas will be welcome.
Thx
Christian
