Ondrej Skutka commented on JBSEAM-4669:
---------------------------------------

Strange. We have stress-tested Seam booking after the JBSEAM-2419 patch and it worked fine. And it didn't work before the patch. Does
ConcurrentFactoryTest pass? 

Maybe the deadlock bug is caused with something else. Can you reproduce it? Do you have a test for it?

> To address JBSEAM-2419, the Component.getInstanceFromFactory(String name) is now "synchronized"
> This causes java deadlocks under stress with the call to lock.lock() in BinjectionInterceptor ...
> For us our apps freezes after 10 minutes in production,,,
> I don't know why this method has been marked as synchronized but this is the cause of the deadlock...
