well .. looks like it may not be a drools issue …

in my log file, I see this
Jan 17, 2012 1:53:10 AM org.activiti.engine.impl.ProcessEngineImpl <init>
INFO: ProcessEngine default created
Jan 17, 2012 1:53:10 AM org.activiti.engine.impl.ProcessEngineImpl <init>
INFO: ProcessEngine default created

Is this normal ? Why is the engine being initialized twice. Would it lead to excess class loading ?

thanks

Hi,

That you get the process engine startup message two times is not a good sign.
However the permgen error is probably related to the fact that it needs an Activiti Engine AND a Drool Engine when you're using rules.
So that could be easily solved by increasing the memory on your build server.

Best regards,
