Description hieronimos.phronesis

2010-06-02 22:21:44 EDT

Build Identifier: M20100211-1343

in the .metadata/.log file I have:
!ENTRY org.eclipse.core.resources 4 2 2010-06-03 10:00:19.149
!MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.core.resources".

I had to manually delete the .metadata/org.eclipse.resources/.snap then eclipse could be launched. Ask me the .snap file by mail if you need it.


Reproducible: Didn't try

Jay, please follow up. Thanks!

Comment 3 Srikanth Sankaran

Jay, Can you take a look at this bug ASAP and see if it needs to be
forwarded to platform/resources ? Since the concerned snapshot files
belong to resources plugin and since when they are deleted the problem
goes away, the smoking gun points to platform resources project and
it may be expedient to forward it to them for comment.

Comment 4 Jay Arthanareeswaran

2010-06-03 13:52:02 EDT

Other than the NoClassDefFoundError, I don't see any relevance to JavaModelManager. Moving to Platform/Resources for investigation.

Comment 5 James Blackburn

2010-06-03 13:57:44 EDT

Was that the only exception in the .log?

A thread dump would help to investigate the issue. Please attach one using the tips from http://wiki.eclipse.org/How_to_report_a_deadlock

Comment 11 hieronimos.phronesis

I notice that sometimes eclipse starts without hanging. It's probably a race condition problem somewhere. I would really enjoy debugging it myself but I don't know anything about eclipse internal. I don't even know where to start ... Any advice?

Comment 12 Pawel Pogorzelski

I assume that having a .snap file persisted cause Eclipse to launch a build early in the startup. This causes initialization of Scala plugin which ends up throwing an exception (java.lang.ExceptionInInitializerError at UIPlugin.scala:558) and leaving workbench in a partially initialized state.

Could you attach a screen illustrating how the workbench looks like when the hang happens? Are you sure it's a hang and not partial initialization? Also, could you uninstall Scala plugin and check if the problem still appears?

Comment 13 Szymon Ptaszkiewicz

As described in comment 12 this looks like a problem with initialization of Scala plugin. Closing as NOT_ECLIPSE. Please reopen with the requested info if you see this again.
