Hi,
Eclispe Mars update 1
Egit 4.0.3
Windows
We get quite a few rename error (jar-files) when we do pull. This is the scenario:
1) Switch branch
2) Eclispe start to build
3) Pull changes
4) Boom, rename error

Since I've seen some bug report for this problem, that is still unsolved, I tried one of the suggestions in one of the bug reports to use file-leak-detector-1.8-jar-with-dependencies.jar (http://mvnrepository.com/artifact/org.kohsuke/file-leak-detector/1.8) to track who is holding a lock to the file that can't be renamed. And I got the following perhaps interesting trace.

Now I know its not the same file as in the error trace but both of these files was changed during the branch switch so both would need to be re-indexed.
Can it be so simple that it's a race condition between the jar indexer and jgit?
Are there any way to confirm this (turn of jar-indexer?) Maybe git pull must wait for jar-indexer jobs?
