In my previous post I described how to get a EE6 web application using the ZK3.6.3 framework on Glassfish V3. I noted while redeploying or undeploying the web-application it made the GF instance plus the JVM crash (running Ubuntu 9.04,9.10 and JDK 1.6.b16).
This problem does NOT exist anymore with the latest build from last week. Make sure you update to build b72. Start the updatetool in glassfish-home/bin. (you might have to start it several times, I got several times time-out errors, or better click on the reminder if you choose the automatic update check feature).
