Description Jens Baumgart CLA 2010-04-29 11:55:15 EDT 
This problem is not always reproducable. You have to execute Team->branch multiple times very fast.

The branch operation fails with:

Caused by: java.io.IOException: Could not rename delete old index
	at org.eclipse.jgit.lib.GitIndex.write(GitIndex.java:296)
	at org.eclipse.egit.core.op.BranchOperation.writeIndex(BranchOperation.java:126)

I could reproduce the problem in the debugger (see attached stack trace). 
The problem is that GitIndex.write can not delete a file that is read by DirCache in the decorator thread.

Just hit this today. The error message should also be corrected as "Could not rename delete old index" doesn't make any sense.
