Created attachment 625653 [details]
Simple Maven based reproducer.

Using CommandFactory.newInsertElements() together with stateless knowledge session results in memory leak _when_ jBPM dependencies are on classpath.
Without jBPM dependencies memory leak is gone.

Version-Release number of selected component (if applicable):
5.3.1-ER3 and earlier.


Steps to Reproduce:
1. Download and run (mvn test) attached Maven based reproducer.
2. See the output that says how much heap memory is currently used.
  

Actual results:
Memory consumption is raising.

Expected results:
Memory should me approximately same after each loop execution.
