[jira] [Commented] (XALANJ-2169) Functions on Nodes in NodeList fail with java.lang.ArrayIndexOutOfBoundsException: -1

    [ https://issues.apache.org/jira/browse/XALANJ-2169?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=18018132#comment-18018132 ] 

Uwe Schindler commented on XALANJ-2169:
---------------------------------------

FYI: The bug has been resolved in the JDK: https://github.com/openjdk/jdk/commit/4b9b3c027faee607fd54953020989106209eb47f

XALAN-J still has the old code. The code in JDK is still Apache Licene 2.0, so we can just apply the same fix here.

> 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
