The crashrecovery12 tests intermittently fail when running on HornetQ journal based object store, i.e. in ExecutionWrapper mode.
Without any patch Test03 and Test06 fail. With my patch, see attached file, the tests fail intermittently, i.e. once they fail on Test02 , once on Test04  or on Test03 . The Test06 seems to be fixed with my patch.
I did the patch according to instructions by Jonathan, but apparently I missed something.
The tests are wrong.
When in ExecutionWrapper mode, each spawned task gets its own store
unless it's explicitly told to reuse an earlier one. Most crash rec
tests that need to 'share' a store between consecutive processes for
before/after crash state have a final param to createTask that gives the
shared name, see e.g. TestGroup_crashrecovery02_01. That's missing in
the failing tests. Change the tests to add the same string as a final
param to the createTask calls and to ensure the client task is
terminated before the outcome task starts. It should be anyhow as it
commits suicide, but the framework does not necessarily know that and
may get unhappy if it think you're trying to make concurrent processes
use the same store.
