[ http://nagoya.apache.org/jira/browse/XALANJ-1352?page=history ]
Henry Zongaro updated XALANJ-1352:
----------------------------------
Priority: Major (was: Blocker)
> DTMManager.getDTM(int) sometimes returns null for RTF
> -----------------------------------------------------
>
> Key: XALANJ-1352
> URL: http://nagoya.apache.org/jira/browse/XALANJ-1352
> Project: XalanJ2
> Type: Bug
> Components: DTM
> Versions: CurrentCVS
> Environment: Operating System: Windows NT/2K
> Platform: All
> Reporter: Morris Kwan
>
> I saw a NullPointerException in the testcase
> extensions\library\libraryNodeset03.xsl when propagating the extension
> changes
> to Xalan3. The weird thing is that this problem has nothing to do with the
> changes I made. It is also intermittent. I can reproduce it on the command
> line. But the problem disappeared when running inside the debugger. Adding
> another unrelated command line option can also cause the problem to disappear.
> I finally traced the problem down to
> org.apache.xpath.objects.XRTreeFrag.finalize(), which calls the destruct()
> method to release the DTM associated with the RTF. The problem is the DTM can
> still be referenced after it is released, causing DTMManager.getDTM(int
> nodeHandle) to return NULL. The finalize() method is called by GC, which
> explains the undeterministic behavior of this bug.
> I think the main branch also has this problem although I only saw it in the
> xslt20 branch.
