Recent release of xml-apis.jar?

Using:
JDK 1.5.0_17 (was using 1.5.0_9)
xalan 2.7.0

Long story short - I want to use xml-apis.jar to get around a defect still present in JDK 1.5.0_17.  However, the last release of xml-apis.jar has a classloader versus systemclassloader defect that was resolved in JDK 1.5.0_11.

JDK bug entry: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6354969
XML Commons bug entry: https://issues.apache.org/bugzilla/show_bug.cgi?id=41931 

Bug 41931 was fixed in xml-apis.jar over 2 years ago.  However, it seems that the last release of xml-apis.jar was 11/2006.

In order to get a version of xml-apis.jar that includes a fix of bug 41931 should I just grab the v1.3.04 tag out of SVN and patch it with the fix for bug 41931?  Or should I just grab a more recent release of the reference implementation from https://jaxp.dev.java.net/?

Although I am not a stranger to building from source, a 2+ year lag from the last release seems to indicate that this project is "dormant".

Best regards,

Carlos

JDK defect I am trying to resolve: 

XPathFactory.newFactory assumes wrong format for META-INF/services entry -

Although the bug was fixed some time ago, the bug details suggest that it was only applied to JDK 6.
