Symptoms

Deploying an EAR application in WLS 10.3 and then undeploying the application, followed by garbage collection (GC), does not bring down the GenericClassLoader (GCL) count.

The issue can be seen by deploying the sample ear application (MedRec) and observing the classloaders. After it is deployed, the total number of GCL objects goes up to 48.

Deleting the EAR application and issuing a GC does not lower the GCL count, remaining at 48. After deploying another (different) EAR application, the GCL count goes up to 80, the number remains unchanged after removing the application.

The GCL count always increases and never decreases.
