java.lang.ClassFormatError: Illegal classname

The CDI TCK passes all tests when run using Glassfish 3.x with Oracle's JDK
1.6.0_24. However, when we change to use Oracle's JDK 1.6.0_25 patch, deployment of some of
the test war files to the autodeploy directory of Glassfish results in the errors below. Talking with Pete Muir, it appears that the JDK has tightened something and is now exposing a bug in Weld.
