After using C git on the same repository, the jgit cache read threw an EOFException, and left the index lock file. The repository is still valid according to C git, but unreachable by C git because it honors the lock file left behind by jgit.

Hi, hope this helps.
The reason for the EOFException is beyond me right now. It reported "Short read of block." However, I'm pretty sure leaving the lock file in place is an error.
