What could be causing the following error from the Jazz Build Engine?

TIA,
J.-P. 

Accepting changes into workspace "Server's Workspace for Automated Builds" ...

Fetching files to fetch destination "C:\autobuild" ...

Thanks nedgar. We found out this was due to a file committed from a Mac whose name contained a colon; file creation failed on Windows. So mea culpa! :-)

Could JBE output a message indicating which file is causing a problem, instead of throwing a NullPointerException? This would sure be more helpful.

I've filed 95644: NPE in MergeLoadMutator.execute when file name contains illegal character for improving the error handling here, and subscribed you and tonio.

Note that this is a general SCM issue (i.e. could also be encountered when loading a workspace in the IDE), not specific to JBE.

Thanks, Nick. That's true; we probably would have spotted the problem before, had we used a regular Windows machine with it other than the headless build server.
