Doesn't happen all the time. Seems to involve a lot of different wtp parts

Comment 3 Rob Stryker

2009-06-30 05:07:41 EDT

If the deadlock is occurring, teh symptom is that "Initializing Java Tooling" never ends, with a subtitle of "Configuring org.eclipse.jst.j2ee.internal.module.container". 

I can immediately still type in an editor, however if I attempt to click in the "navigator" view, or activate hte navigator view, the UI thread freezes in org.eclipse.wst.sse.core.internal.propertytester.testContentType(IFile, String) checking if one of the component.xml files is of content type org.eclipse.jst.jsp.core.jspsource  (small trace to follow)

Comment 4 Carl Anderson

2009-06-30 16:56:55 EDT

Jasoh Sholl just fixed some deadlocks during initialization of the container- assigning this to him for the initial investigation.

Comment 5 Rob Stryker

2009-07-21 13:23:47 EDT

This deadlock is becoming really hindering to my dev and testing. Sometimes even in a workspace wityh just one modulecore project it's occurring.

Comment 6 Rob Stryker

2009-07-24 15:47:19 EDT

Jason:

Is there a build where your deadlock issues have been fixed that maybe I can make use of or test out? ;)  THis is really impeding my dev time =]

Comment 7 Jason Sholl

2009-07-27 11:02:38 EDT

I haven't had a chance to look at this yet.  I did make several changes to the initialization of the EAR Libraries classpath container a few weeks ago, but all these changes should already been in the builds.  If you're self hosting and have org.eclipse.jst.j2ee, then you have all the changes.

Comment 8 Rob Stryker

2009-08-20 17:50:21 EDT

were these changes added to teh wtp 3.1.x maintenance branch?

Comment 9 Jason Sholl

2009-08-24 09:58:05 EDT

No, these changes I was referring to are in 3.2.

Comment 10 Carl Anderson

2009-09-03 15:00:08 EDT

The fix for this would be of considerable size, and it is very late in the WTP 3.1.1 development cycle to release such a large change.  (This may be fixed by bug 287763, if that makes it into 3.1.1)

Comment 12 Dani Megert

2009-09-21 09:36:59 EDT

FYI: some of the deadlock stack traces are related/caused by bug 283163 in the SDK which got fixed for 3.5.1.

Comment 13 Jason Sholl

2009-11-19 14:42:37 EST

I think both this bug, bug 288619, and bug 287763 may have been fixed by bug 291143 with the introduction of IJavaLite.  If you can still reproduce this with the latest 312 code (not sure if this has been released to the builds yet), please reopen with new stack traces.
