Cannot download jar file from working directory when distributed build enabled

Whenever I am trying to download a jar file from the working copy page of continuum and the distributed build is enabled, I am not able to do so. I am able to download non-jar files. The working copy page shows nothing, but I am seeing some exception in the log. Please find attached the log. Also, I am not getting any error to download the jar files if distributed build is disabled. For other non-binary files, I do not see any problem. Let me know if there is any fix available for this issue.

Thanks,
Bodhayan.
