I'm not sure, if this is the right place to ask, but I ran into a deadlock on Eclipse startup. Here is my environment:
Windows 7 64-bit
Sun/Oracle JDK 1.6.0u33 32-bit
Eclipse Java EE IDE for Web Developers 32-bit
Version: Juno Release
Build id: 20120614-1722

Installed plugins:
STS 3.0.0
AJDT 2.2.1
Findbugs 2.0.1
PMD 3.2.6
Checkstyle 5.5
Subversive 1.0 + SvnKit 1.3.8 + JavaHL 1.6.15
Maven Integration for Eclipse m2eclipse 1.1.0
Maven Integration for WTP 0.15.2
Hibernate Tools 3.5.1
Structure101 3.5.3728
JD Decompiler 0.1.3 + JD Eclipse Realign 1.0.8
RegexUtil 1.2.4
PlantUML 1.0.7.7933
Workspace Mechanic 0.3.2

I'm not sure, if a plugin is causing this or if it's a Eclipse core issue.

Anyway, attached is the threaddump.

Killing the process and restarting Eclipse worked, e.g. I got no deadlock again.
Please let me know if you need more info.

Thanks,
Holger

I see a very likely candidate:

You have AJDT installed.
One of the blocking threads mentions org.eclipse.equinox.weaving.hooks.WeavingLoaderDelegateHook, which is what AJDT uses for loadtime bytecode weaving.
This technology is known to potentially trigger cyclic class loading dependencies.
As far as I remember, AJDT avoids these cycles by heuristically pre-loading certain bundles, but that is known to be an incomplete situation.
I don't remember the bug number but there exists a bug against AJDT regarding this issue.
On a JVM >= 1.7 actually cyclic class loading should not be a problem, but the AJDT weaver itself does not allow reentrance.
I hope the AJDT folks can advise you how to avoid the deadlock in your situation.

best,
Stephan

Thanks Stephan for the hints.
Unfortunately, this bug isn't reproducable.
Nevertheless, I'll enter a bug report.

Yesterday, I had another deadlock in the SVN Synchronize View when reverting some changes. But I couldn't take a threaddump, because jstack and visualvm where not able to connect to the Eclipse process.

I think we'll move to the Eclipse 3.8 version and see if it's more stable and performant.

I believe the AJDT folks should already be able to draw some conclusions from the stack trace you pasted before.

Good luck,
Stephan

FWIW, none of the code involved in these deadlocks is any different between 3.8 and 4.2.

I agree that in this issue 3.8 vs. 4.2 isn't the main factor.

OTOH, the way in which AJDT's load time weaving interacts with on-demand class loading and bundle activation makes it potentially vulnerable against any change in the environment. I wouldn't be surprised if the same setup is stable on 3.8 and unstable on 4.2, although not linked by direct causality.

As reference, here is the bug report:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=389659

It is marked as duplicate of bug 212262.

One solution seems to be to run Eclipse on top of JRE 7.

Thanks for your assistance.
