Memory leak with simple example code
------------------------------------

                 Key: JBPM-827
                 URL: http://jira.jboss.com/jira/browse/JBPM-827
             Project: JBoss jBPM
          Issue Type: Bug
          Components: Core Engine
    Affects Versions: jBPM 3.1.3,  jBPM 3.1.2
         Environment: java 1.4.2

            Reporter: Johan Parent
         Assigned To: Tom Baeyens


The Websale example wrapped in a simple for-loop in standalone app. reveals what resembles a memory leak. Performance degrades severely as the JVM starts to do some expensive gc after 4000 iterations. At that time the JVM consume more than 274Mb of ram (JVM not started with special -X options!)

Problem occurs with HSQLDB as well as Sybase db.

The code to reproduce this problem has been posted here http://www.jboss.com/index.html?module=bb&op=viewtopic&t=99440
