Deadlock in ProjectClassLoader

The concern is specifically a deadlock on org.drools.core.common.ProjectClassLoaders:

"http-0.0.0.0:8443-90":
  waiting to lock monitor 0x00007f25900045e8 (object 0x00000000b77253d0, a org.drools.core.common.ProjectClassLoader),
  which is held by "http-0.0.0.0:8443-122"
