1.4.2_12 b01Fixed
Description
The bug which has existed since day one, was revealed recently in
1.4.2_12 because of the addition of new asserts (as part of
6316988) and because of new testing (ATG/PIT and ATG/Startup testing).

The bug can cause infrequent heap corruption and JVM crashes
that are hard to diagnose.
Comments
WORK AROUND There is no know workaround, ecept to stop using the CMS collector.
