[jira] Commented: (XALANJ-2439) [PATCH] XSLTC resource leak causes
'No more DTM IDs are available' error
[ https://issues.apache.org/jira/browse/XALANJ-2439?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12833005#action_12833005 ]
Henry Zongaro commented on XALANJ-2439:
---------------------------------------
As with bug XALANJ-2438, it seems there is some code derived from Sun's reference implementation of JAXP in a jar file attached to this bug report: DOMLeak-XSLT-Test-1.0.jar. May I ask you to remove that code, since it's licensed under different terms than the Apache license? Because you've accessed Sun's reference implementation, I won't be able to review your patches, as they might contain code that's covered under Sun's copyright. As I am not an employee of Sun or Oracle, I don't have the authority to contribute Sun copyright code to the Apache project. Only an employee of Sun or Oracle who has signed an Apache CLA can contribute such code.
Thanks for your understanding,
Henry

> Key: XALANJ-2439
> URL: https://issues.apache.org/jira/browse/XALANJ-2439
> Project: XalanJ2
> Issue Type: Bug
> Components: XSLTC
> Affects Versions: The Latest Development Code
> Environment: Linux and Windows XP with Sun JRE 1.5.0_15 and 1.6.0_05
> Reporter: Helge Schulz
> Priority: Minor
> Fix For: The Latest Development Code
>
> Attachments: DOMLeak-4-NodeSetAndMultiDOM.xsl, DOMLeak-Xalan-SVN-r584164.patch, DOMLeak-XSLT-Test-1.0.jar
>
> Original Estimate: 4h
> Remaining Estimate: 4h
>
> The Xalan XSLT compiler (XSLTC) has several resource leaks in handling
> result tree fragments in XSLT variables and parameters. If a variable
> or parameter declaration contains XML elements, a new DOM tree is created
> and a new internal integer id is reserved for it. The garbage collector can
> never retrieve this DOM tree, because the id registration holds a reference
> to it. This bug prevents the transformation of large input files, because
> complex templates creates many result tree fragments and exceeds often the
> absolute limit of possible DOM trees in XSLTC (2^16 = 65535). If this
> limit is reached, XSLTC throws the following exception:
> DTMException: No more DTM IDs are available
> The attached patch adds a new release method to the DOM interface and calls
> it, when the scope of a variable or parameter is leaved.
> You can test this patch with the attached JAR file. This file can be
> called with
> java -Xmx800M -jar DOMLeak-XSLT-Test-X.Y.jar
> This file contains four test style sheets with expected output files.
> This bug exists also in *all* Sun JRE 1.5 and 1.6 versions, because the
> Xalan XSLTC source code is used in the 'com.sun.org.apache.xalan.internal'
> packages. The attached test JAR file contains also a patch for the current
> Sun JRE version 1.6.0_5 and a fix JAR file to be installed into the
> '../jre/lib/endorsed' directory of the JRE installation.
> Please add the attached test files to the Xalan test suite. I have
> released them under Apache license version 2.0.
