The BugDB bug was filed against jdk5_16. I'm adding this report to record the fact that I've fixed it in jaxp 1.4.5 update 1 and will integrate into jdk7.

Original report:
The XSL Transformations of XSLT files which are large (128 KB and larger)
  are failing with Java 1.5 with the following error:
can't process xslt: Could not load the translet class 'GregorSamsa'.
