#1538 lock.test.EnterpriseEntityStressTestCase fails under load
MacOSX 10.2, JDK 1.4.1, JBoss 3.2 latest from today.
When you run "tests-stress" in the testsuite directory with
the original settings, the test works fine.
It fails when the test is configured to run longer, and with
more threads, using the attached file that needs to be saved
in the testuites directory as ".ant.properties" to reproduce
the problem.
On the client-side, the following trace appears:

This is a bad test.
The error occurs when running with commit option D.
It could occur with any cache invalidation.
The test entity bean has state, but it is not persisted.
A cache invalidation leads to an NPE when the state is accessed.

Adrian
