1. Re: JBoss Knowledge Base Builder hangs in Eclipse
zovitsa Feb 15, 2012 8:52 AM (in response to zovitsa)Since then I managed to bypass the problem by uninstalling all eclipse plugins that contained the "jboss" string in their names. However I think this is quite far from the ideal solution.

3. Re: JBoss Knowledge Base Builder hangs in Eclipse
zovitsa Feb 15, 2012 12:53 PM (in response to akazakov)There is a stack trace in the attached zip, named eclipse.log. If that doesn't contain the necessary information then I'm afraid I won't be allowed to reinstall everything again just to reproduce this error.

akazakov Feb 15, 2012 1:03 PM (in response to zovitsa)Unfortunately eclipse.log is just a log of exceptions. It's very hard to figure out what was the reason of this hang-up without stack trace of all the java threads. Can you remember what you did before this happened? Created some project or what?

5. Re: JBoss Knowledge Base Builder hangs in Eclipse
zovitsa Feb 16, 2012 4:21 AM (in response to akazakov)It happened right after I reverted all the projects to JDK 1.6.0. Could that be the cause?

6. Re: JBoss Knowledge Base Builder hangs in Eclipse
maxandersen Feb 21, 2012 7:45 AM (in response to zovitsa)1 of 1 people found this helpfulit could be the "trigger" since it possibly caused a full rebuild of all projects and maybe something in your project layout/dependency list somehow triggers a bug in the builder.
Any chance you can force the bug by cleaning all projects at once ?
Then when it freezes use jstack to capture the blocked/busy threads ?

7. Re: JBoss Knowledge Base Builder hangs in Eclipse
zovitsa Feb 21, 2012 10:11 AM (in response to maxandersen)I tried my best to restore the original (buggy) state of my Eclipse instance, including reverting all files (projects, settings, runtimes, etc) to that revision but I couldn't reproduce the bug again. Probably something has managed to evade my attention...
Anyways, thank you for the jstack hint, I'll definitely use it next time when I encounter such an error.

zovitsa Feb 27, 2012 5:19 AM (in response to maxandersen)Hi again!
Today I managed to run into this issue again, and this time I could obtain the jstack traces of the relevant threads.

akazakov Feb 27, 2012 12:11 PM (in response to zovitsa)Thanks for the stacktrace! I see that JBoss tools is downloading XML schemas (or may be DTD) to parse some XML from the jars from your project. It looks like a bug.

akazakov Feb 27, 2012 12:16 PM (in response to akazakov)I've created an issue in JIRA - https://issues.jboss.org/browse/JBIDE-11066

11. Re: JBoss Knowledge Base Builder hangs in Eclipse
zovitsa Feb 28, 2012 3:20 AM (in response to akazakov)Now that you mention it... My Eclipse instance has various errors (mainly stalling) associated with downloading files, be it plug-in descriptors from update sites or packages from our intranet. But I'd have never suspected this to be connected to the original issue.

akazakov Feb 28, 2012 3:27 AM (in response to zovitsa)Adam, I don't know what causes those problems with internet connection but Knowledge Base builder should not trigger any downloading while scanning JARs anyway.
