[jira] Commented: (XALANJ-2169) Functions on Nodes in NodeList fail with java.lang.ArrayIndexOutOfBoundsException: -1
[ http://issues.apache.org/jira/browse/XALANJ-2169?page=comments#action_12315663 ]
Brian Minchau commented on XALANJ-2169:
---------------------------------------
Problem was reproduced by Henry Z.
There are either nodes from multiple DTMs involved, or something like that.
There is a DTM associated with the node list that is different than the DTM for the particular node that is involved.
Perhaps a constructor is being invoked with the wrong DTM specified.
The DTM is being asked for information about a node and it is not the DTM that owns the node.
Not sure if there is a work around for this one.

> Key: XALANJ-2169
> URL: http://issues.apache.org/jira/browse/XALANJ-2169
> Project: XalanJ2
> Type: Bug
> Components: Xalan, XSLTC, DTM
> Versions: 2.6
> Environment: Java 1.4.2_06; Xalan 2.6.0; Xerces 2.6.2; Windows 2000
> Reporter: Glen Blanchard
> Attachments: Extension.java, booklist.xml, 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
