The following regression test fails intermittently in nightly on some Linux machines:
  java/lang/instrument/TransformerManagementThreadAddTests.java

> New INSTRUMENT_REGRESSION failures (from 2007.06.07)
> * java/lang/instrument/TransformerManagementThreadAddTests.java
> This test failed because a transformation appeared in an
> unexpected order on Linux IA32 Client VM (machine jck-win5).
> Bug 4926961 talks about a bad assumption about the addition
> of transformers. I wonder if this is the same bug.

This is the error log below:

----------System.err:(19/1467)----------
