lombok deadlocks eclipse

GoogleCodeExporter commented 9 years ago

lombok version: 0.11.8
eclipse version: indigo
os: ubuntu 12.04

A deadlock occurs consistently and shortly after start up after I stalled 
lombok.

org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader gets blocked on 
lombok.patcher.equinox.EquinoxClassLoader which in turn is blocked on 
org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader

Relevant stack traces:

Any work arounds?

I have no idea if this fixes things, but we changed a lock that's near the 
stacktrace you've given us. Can you give it a shot and see if this solves the 
problem?

edge release with the fix is here:

Shame we didn't get any feedback. More reports on something that looks similar 
have come up. We've eliminated one of the locks.
