[Panagiotis Korros]

I got the a deadlock while starting up eclipse, I had to kill the eclipse process in order to continue working.

The vm stack trace is:

Found one Java-level deadlock:
=============================
“All Types Caching”:
waiting to lock monitor 0x009bf26c (object 0x10ec5ab0, a org.eclipse.core.internal.preferences.DefaultPreferences),
which is held by “Thread-1”
“Thread-1”:
waiting to lock monitor 0x009bf2ac (object 0x11293938, a org.eclipse.jdt.internal.core.JavaModelManager),
which is held by “All Types Caching”

Found 1 deadlock.

– System Setup ——————————-
Operating System and version: Windows 2003 Server
Eclipse version: 3.0.1
Eclipse build id: 200409161125
Fresh Eclipse install (y/n): y
If not, was it upgraded to its current version using the update manager?
Other installed external plugins: no
Number of plugins in the <eclipse>/plugins directory that begin with org.eclipse.pde.*: 8
MyEclipse version: 3.8.3
Eclipse JDK version: 5.0
Application Server JDK version: 1.4.2
Are there any exceptions in the Eclipse log file? no

[Riyad Kalla]

Try and restart Eclipse by adding the -clean command line argument, see if this problem is caused by stale plugin cache info.

[Panagiotis Korros]

This is not a permanent problem. When I restarted everything worked correctly.

[Riyad Kalla]

This is not a permanent problem

How many restarts does it take usually before the problem comes back? Can you reproduce it with 5 restarts? 10 maybe? Let us know if it comes back.

[Panagiotis Korros]

I don’t really know. It happens to me every 8-10 times.

[Riyad Kalla]

… well then that is officiall ‘odd’. I’ve never experienced a deadlock in the Eclipse platform, let me check with the other devs to see if they have during development.

[Panagiotis Korros]

MyEclipse froze again at startup with the same configuration as above.

One thing I can think of is that I personally saw some odd behavior with earlier versions of the 1.4.2 JDK that were resolved by upgrading to the latest one 1.4.2_06-b03. I never saw this particular issue, but there was some other strangeness that went away. Can you try that to see if it resolves the issue?
