Build Identifier: 

We're trying to use EGit/JGit with a repository imported from CVS that has some large files in it (200MB). At least that's what I suspect is the reason. Cloning fails after some time with this Exception:

tried with the current nightly (0.9.0.201007271530)

This also happens when trying to merge large files (around 10MB).

Can you retry this with a 0.10 nightly?

This could be a legitimate bug.

Comment 4 Ionut Prunache

I'll give it a try when i will have some spare time.

This seems to be a common problem and occurs when trying to call ObjectLoader.getBytes when dealing with large files. I think the same problem was handled on bug on EGit: Bug 322707.
