Thomas Leung commented on DROOLS-890:
-------------------------------------
Hi, I'm in same team as Vivek. In the log there are 2 locks, one is the
ProjectClassLoader and another is an inner class object
ProjectClassLoader$InternalTypesClassLoader. So seems like thread 48 waiting to lock
ProjectClassLoader (which is locked by thread 31) and thread 31 waiting to lock
ProjectClassLoader$InternalTypesClassLoader which is locked by thread 48.
While we are trying to test against 6.2.0.Final version, can you see if the above log
bring you some idea on the cause?

In our project , we are using drools6.1.0.Final jars and the rules are deployed in a jar.
Another application when trying to use the rules jar is getting thread deadlock problem.
Stack trace is
at
org.drools.core.common.ProjectClassLoader$InternalTypesClassLoader.loadClass(ProjectClassLoader,java284)
Two threads are in deadlock condition on this thread. I restarted the application and the
error is gone but we need to fix this issue so that it is not reproduced later.The class
is in drools-core jar
