Description Jakub Filak 2013-09-27 08:36:01 UTC 
+++ This bug was initially created as a clone of Bug #1012545 +++

Description of problem:
All abrt-java-connector event callbacks enter a single private critical section. Some callbacks may trigger a GC run while being in the critical section. The GC start callback also wants to enter the critical section but the critical section is locked because the triggering callback waits until the GC run finishes. So both callbacks are waiting for each other.

Version-Release number of selected component (if applicable):
abrt-java-connector-1.0.5-1.fc19

How reproducible:
Accidentally

Steps to Reproduce:
1. run a sufficiently big application for a sufficiently long time
