Description Robert Oschwald CLA 2010-11-19 08:19:34 EST 
Build Identifier: Version: 3.6.0.v20100602-9gF78GpqFt6trOGhL60z0oEx3fz-JKNwxPY Build id: I20100608-0911 (cocoa 32bit)

Suddently, when I restarted Eclipse, it freezes on "Update SVN Cache".

I then moved one project on the filesystem away and restarted successfully. Project is in "closed" state then. Moved it back and opened project without a problem.

Versions:
  Subversive SVN Team Provider (Incubation)	0.7.9.I20100512-1900 org.eclipse.team.svn.feature.group
  SVNKit 1.3.2 Implementation (Optional)	2.2.2.I20100512-1900 org.polarion.eclipse.team.svn.connector.svnkit16.feature.group
  SpringSource Tool Suite	2.5.0.201008251000-M3	com.springsource.sts.ide
  Eclipse Platform	3.6.0.v20100602-9gF78GpqFt6trOGhL60z0oEx3fz-JKNwxPY	org.eclipse.platform.feature.group (cocoa 32bit)

I attach thread dumps to this case.

Reproducible: Sometimes

Steps to Reproduce:
1. close Eclipse with some SVN projects open in Java view
2. restart Eclipse
3. Eclipse hangs on "Update SVN Cache" with spinning wheel.

Threads were blocked at native library loading. So, it looks more like an system-level issue (JVM problems or problems with the libraries being loaded). And unfortunately there is nothing we can do.

One note:

We have this problem on all our OSX 10.6.x machines from time to time.
The lock only occurs when many Eclipse SVN enabled projects are open.
Comment 4 Alexander Gurov CLA 2010-11-27 10:05:29 EST 
Probably the issue is related to some library which is loaded by SVN Kit client. In that case as a possible solution you could try switching to the JavaHL client.
Comment 5 nukeevry1 CLA 2011-01-07 09:27:09 EST 
A number of developers at my organization are seeing this on Mac OSX 10.6 and Windows 7 as well using SVNKit.
