[rules-users] Noob desperately needing help

[Mattias Nilsson Grip]

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.

Did you try to debug your code to see exactly where the hung is? zip4j seems to be open source, you could even debug its internals to see where the problem is and maybe you can get a clue of what is going wrong.

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...
