Re: [eclipselink-users] Deadlock issue of JPA 1.0
|
This seems to be a known (and already fixed) bug in eclipselink, see:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=321473
So maybe upgrading to EclipseLink 2.2 is an option for you.
And please note that it's not a classic (synchronization) deadlock - but a "wait
forever" (lack of notify()) situation which has a similar outcome of a deadlock.
When looking at the provided patch of the bug, I don't think that there's an
easy workaround to resolve the problem.
