The problem is this method in
MultiDOM
public NodeList makeNodeList(DTMAxisIterator iter) {
// TODO: gather nodes from all DOMs ?
return _main.makeNodeList(iter);
}
It uses the _mail always when it should use the DOM from which the iter is from.
I.e. it should probably be something like:
public NodeList makeNodeList(DTMAxisIterator iter) {
// TODO: gather nodes from all DOMs ?
if (iter instanceof MultiDOM.AxisIterator) {
return _adapters[((MultiDOM.AxisIterator)
iter)._dtmId].makeNodeList(iter);
} else {
return _main.makeNodeList(iter);
}
}
disclaimer: this is the first time I had a look at Xalan code, so I might be
completely off with my solution proposal.

> Key: XALANJ-2169
> URL: https://issues.apache.org/jira/browse/XALANJ-2169
> Project: XalanJ2
> Issue Type: Bug
> Components: DTM, Xalan, XSLTC
> Affects Versions: 2.6
> Environment: Java 1.4.2_06; Xalan 2.6.0; Xerces 2.6.2; Windows 2000
> Reporter: Glen Blanchard
> Attachments: booklist.xml, Extension.java, test.xsl
>
>
> When using an extension over a RTF converted to a NodeList using the nodeset
> extension function, some methods on the Nodes in the NodeList throw and
> java.lang.ArrayIndexOutOfBoundsException: -1
> Tracing through the code it comes down to the DTMDefaultBase.makeNodeIdentity
> function returning a DTM.NULL because the nodeHandle passed in doesn't belong
> to "this" DTMDefaultBase instance.
> Comment extracted from DTMDefaultBase:
> // %REVIEW% Wish I didn't have to perform the pre-test, but
> // someone is apparently asking DTMs whether they contain nodes
> // which really don't belong to them. That's probably a bug
> // which should be fixed, but until it is:
> if(m_mgrDefault.m_dtms[whichDTMindex]!=this)
> return NULL;
> The full call path is:
> Caused by: java.lang.ArrayIndexOutOfBoundsException: -1
> at
> org.apache.xml.utils.SuballocatedIntVector.elementAt(SuballocatedIntVector.java:438)
> at
> org.apache.xml.dtm.ref.DTMDefaultBase._firstch(DTMDefaultBase.java:526)
> at
> org.apache.xml.dtm.ref.DTMDefaultBase.getFirstChild(DTMDefaultBase.java:973)
> at
> org.apache.xml.dtm.ref.DTMNodeProxy.getFirstChild(DTMNodeProxy.java:370)
> Let me know if more detail is required as this is the last hurdle for a major
> speed improvement.
> Thanks
