Bill Tuminaro updated DROOLS-1372:
----------------------------------
           Description: 
I have attached a reproducer named UpdateToVersionCreatingNewClassloaders.java that creates a KieContainer with a KieModule that contains a single rule (rule name 1081) and then runs a loop that adds 1 rule and removes 1 rule and calls KieContainer.updateToVersion().  Along the way it creates .dmp files.

If you examine the .dmp files name updrule#_3.dmp (i.e. updrule1_3.dmp , updrule3_3.dmp ) you will see that the number of classloaders for the rule named org.drools.compiler.integrationTests.Rule_10810DefaultConsequenceInvoker increases by 1 each iteration.

Along the way it creates .dmp files.

If you examine the .dmp files name updrule#_3.drl (i.e. updrule1_3.drl , updrule3_3.drl ) you will see that the number of classloaders for the rule named org.drools.compiler.integrationTests.Rule_10810DefaultConsequenceInvoker increases by 1 each iteration.



    Steps to Reproduce: Run the attached reproducer and examine the  updrule#_3.dmp (i.e. updrule1_3.dmp , updrule3_3.dmp )  files that are created. Notice the number org.drools.compiler.integrationTests.Rule_10810DefaultConsequenceInvoker classloaders is increasing.
