Code posting fail....if you want to help, I guess go to the mailing list web site and read the code....sigh.... -- View this message in context: http://drools.46999.n3.nabble.com/Noob-desperately-needing-help-tp4020589... Sent from the Drools: User forum mailing list archive at Nabble.com.

Davide, Thanks for the response…I have also fired the attached code from outside a rule, and it works perfectly (I created a hidden test menu option that allows me to call runNeedleChestDecompressionReport()). In fact, every other instance of using ZipUtil works fine. And the place where the rule is hanging hasn’t actually gotten to the byte array yet…it’s creating internal data structures to handle the input. I’m grasping for straws, I know… Paul -- View this message in context: http://drools.46999.n3.nabble.com/Noob-desperately-needing-help-tp4020589...

Wolfgang, Here's my dilemma...there is no exception thrown! I wouldn't even be here asking the question if I was getting an OOME...my problem is that the rule hangs, and from that point on, the entire rules engine is hung, even though other processing continues on that jboss node. Note that I'm using zip4j, as the default zip library provided in Java does not support password-protecting the zip file. That is a requirement of this process. And this is new code...it works perfectly outside the rules container, but not at all inside it. What baffles me is the process hanging...I've been writing Java code for 13 years, and I've never seen a process just hang...

I was just about to suggest something similar. Use JDB or some other utility to get a thread dump from the JVM when it is hung. That should let you know exactly in what class and method the thread hangs. You could also change your code to catch (and rethrow) Throwable instead of Exception to double-check that the call to ZipOutputStream is not throwing an Error that is secretly caught somewhere without being logged.
