JDK Crashing in AS Build

alrubinger Apr 16, 2009 5:10 PM

Second time in as many days I've crashed the JDK doing "./build.sh clean most" on trunk/Branches_5_x.

Have we seen this before or know of a workaround/fix?

This came up on the jboss-dev list earlier this week. Seems cleaning out the tomcat module's output dir fixed it (don't know why clean wouldn't do that, but...)

Actually now I'm getting it reliably on trunk. :)

I missed that, thanks.

Hmm...cleaning tomcat/target (AS trunk) isn't helping. Using jdk1.6.0_11-x86_64 did the trick this time.

Brian, any idea what could have caused this to start happening?
It seems like it started after your changes in r87304.

It seems that this is a bug in the jdk since newer revs seems to work fine consistently, is this something we need to look into further?

That commit wasn't doing anything really exceptional, except for some generics fun.

It's not good though if it's crashing peoples' builds and requiring a JDK upgrade. But not sure what to do about it. :(

I just had to upgrade from JDK1.5.0_15 to JDK1.5.0_18.

Nice work, Brian showcasing a JDK bug by example. ;)

I have a 1.5.0_16 on my machine that I just reproduced it with; I'll figure out how to add verbose output to the mvn compile process and see if that sheds any light on the issue

Just doing my bit to ensure we all keep up with the latest and greatest. ;)

Verbose mode is our friend. It seems unable to handle the commented out code below so I'm replacing it with the non-genericized stuff below it.

 // Genericized code below crashes some Sun JDK compilers; see
 // http://www.jboss.org/index.html?module=bb&op=viewtopic&t=154175

// Map<ClusteredSession<? extends OutgoingDistributableSessionData>, SnapshotManager> sessions = ctx.getCrossContextSessions();
// if (sessions != null && sessions.size() > 0)
// {
// for (Map.Entry<ClusteredSession<? extends OutgoingDistributableSessionData>, SnapshotManager> entry : sessions.entrySet())
// {
// entry.getValue().snapshot(entry.getKey());
// }
// }

 // So, use this non-genericized code instead
 Map sessions = ctx.getCrossContextSessions();
 if (sessions != null && sessions.size() > 0)
 {
 for (Iterator it = sessions.entrySet().iterator(); it.hasNext();)
 {
 Map.Entry entry = (Map.Entry) it.next();
 ((SnapshotManager) entry.getValue()).snapshot((ClusteredSession) entry.getKey());
 }
 }
 }

With that the problem goes away for me.

I've committed that change to trunk and Branch_5_x.

That fixed it for me using jdk1.5_12. Thanks!
