null pointer errors in server logs

We have a Jazz server that is giving errors when we try to deliver code. I believe this is the corresponding exception in the logs. Does this look like a Jazz bug or a server misconfiguration? Can someone help us diagnose the problem? (Also, I'm not sure if this is relevant, but we are working off of data that was migrated from 0.6M2a to 0.6M3a, and the repository URL changed as a part of that migration)

Doesn't look like a known issue on Jazz.net. Worth opening a defect ...
Oh well, I feel like being nice today... here it is :->

On the client side we are receiveing the following exception when files
are being fetched from the repository when creating a repo workspace
from a stream. Only a portion of the content is retrieved.
