Re: [jgit-dev] JGit checkout of multiple tags fails with "Could not rena

["Andrey Loskutov" <loskutov@xxxxxx>]

Hi,

I've observed not the same but similar issue during tests on Linux NFS mount, where jgit was not (always) cleaning up the opened temporary pack file streams, see [1] for more details.

I didn't found the root cause however. I suspect that if you would add some delay between two checkout calls your issue would disappear, because this was what I've observed in debugger.

Kind regards,
