Why don't you post your patch what is permgen space in java to jdk-collaboration.dev.java.net so at least all JDK contributors can take advantage of it today? Thanks Matthias Posted by Matthias on October how to resolve java.lang.outofmemoryerror permgen space 19, 2006 at 11:30 PM PDT # Excellent blog! Thanks. When we added HAT (as jhat) to JDK 6 we knew it had some problems, but it was such a valuable tool in conjunction with jmap java.lang.outofmemoryerror permgen space tomcat that we felt we needed to include it anyway. Sundar has done a fantastic job fixing some of the problems, and we definitely will accept this fix too. -kto Posted by Kelly O'Hair on October 20, 2006 at 02:40 AM PDT # Thanks for the feedback! I submitted an RFE; see http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6484556 I'll try to upload a patch to jdk-collaboration.dev.java.net (I'm currently waiting for access to this project).

Posted by Nick Stephen's blog on October 30, 2006 at 06:45 PM PST # Today I discovered your blog while googling information about JavaCAPS and transaction handling. Youre articles are very interesting and way better than the documentation delivered with JavaCAPS. Thanks for writing them! There isn't a lot of good information on the more technical aspects of JavaCAPS in the web, so your blog is really helpfull. Posted by Ortwin Escher on November 02, 2006 at 09:10 PM PST # Really helpfull informations, very clear, thanks for sharing. I develop with java 1.4 but with recents releases dumps are compatibles. You say it's possible to ask you for your modified libs. Could you contact me please so that I can get your libs in the next days, I have a very short dead line and I can't wait for next java release.

However it can also be encountered in a recently spawned JVM under the "right" set of conditions. The message is a symptom of an incomplete garbage collection sweep where resources are not properly released upon unload/restart. There is no shortage permgen space of debate (Hibernate forum, Sun forum, Spring Framework forum ) regarding which codebase is responsible for this symptom, but the finger of blame has been pointed at CGLIB, Hibernate, Tomcat, and even Sun's JVM. Generally speaking, this is an interoperability issue and can be resolved by changing one of the components in your software stack. Some users have reported relief error permgen space by upgrading to the latest Tomcat 5.5 release, others have simply opted for another webcontainer implementation (like Jetty or Resin) with varying degrees of success. In my experience, the most pain-free method of resolving this issue is to switch from Sun's JDK implementation to BEA's freely available JRockit implementation. On a recent project utilizing Tomcat 5.5.12 with Hibernate, I was plagued with this PermGen error, at times even experiencing it during web-based unit testing. Since making the switch to JRockit, I have not encountered this issue even once. I attribute the "fix" to the differences between JRockit's and Sun's garbage collection implementations, but have no proof that this is indeed the reason that JRockit resolves the issue. In any case, WFM. Posted by ets ( Jun 23 2006, 11:23:09 AM EDT ) Permalink Comments  Comments: I also had these annoying Perm Gen Space OOMs when redeploying webapps.
