Re: [rules-users] Memory leak in 5.2/5.3

[alopez]

Good news, I followed your advice and patched drools-core to prevent this,
focusing on removing all listeners:

AbstractWorkingMemory.java, line 1246:

for ( Iterator it = this.__ruleBaseEventListeners.iterator(); it.hasNext();
) {
       this.ruleBase.removeEventListener( (RuleBaseEventListener) it.next()
);
}

I changed that to:

for ( Iterator it = this.ruleBase.getRuleBaseEventListeners().iterator();
it.hasNext(); ) {
       this.ruleBase.removeEventListener( (RuleBaseEventListener) it.next()
);
}

And now works OK, no memory leak.

Thanks
