[jira] Created: (SM-1524) Fix for Memory Leak in ServiceMix-Drools4
DroolsEndpoint
Fix for Memory Leak in ServiceMix-Drools4 DroolsEndpoint
--------------------------------------------------------
Key: SM-1524
URL: https://issues.apache.org/activemq/browse/SM-1524
Project: ServiceMix
Issue Type: Bug
Reporter: Roman Stumm
There is a memory leak in class org.apache.servicemix.drools.DroolsEndpoint, because the StatefulSession object must be released, otherwise the drools rulebase keeps a reference to it.
(Description see drools docu:
http://downloads.jboss.com/drools/docs/4.0.7.19894.GA/html_single/index.html#d0e900
Chapter 2.5.5
The StatefulSession extends the WorkingMemory class. It simply adds async methods and a dispose() method. The ruleBase retains a reference to each StatefulSession is creates, so that it can update them when new rules are added, dispose() is needed to release the StatefulSession reference from the RuleBase, without it you can get memory leaks.
)
Here is the fix: (replace methods drools() and createWorkingMemory() with those in org.apache.servicemix.drools.DroolsEndpoint)
protected void drools(MessageExchange exchange) throws Exception {
StatefulSession memory = createWorkingMemory(exchange);
try {
populateWorkingMemory(memory, exchange);
memory.fireAllRules();
} finally {
memory.dispose();
}
}
protected StatefulSession createWorkingMemory(MessageExchange exchange) throws Exception {
return ruleBase.newStatefulSession();
}
