I am uninstalling my Java EE application that uses an asynchronous log that is logged in its thread from the Drools rule engine. I use it to register decisions that the rules engine makes, but I cannot let them affect the throughput, so it should work in its own thread.
I get Exception pages when I divorce it, indicating that it was not closed properly. This may be true as the log is just a thread like this:
while(true){ log(something) sleep(someTime); }
He may not have time to react normally when he is sleeping, and undeploy starts. Unfortunately, I cannot get the stream itself from the registrar, so I cannot join it in the @PreDestroy method. How can I avoid deployment exceptions?
