I have a Hudson build that was failing all my EJB tests, whereas they all ran
fine on my machine.
Racked my brain, and then renamed the job so that the job name--and hence one of
the directories in the path--no longer had spaces in it.
After this point, EJB tests ran fine. Looks like EJBContainerImpl can't deal
with paths to the modules that it deploys with spaces in them.
