RTC v3.0.1.1

What is causing this RTC/JBE  Build problem?

Our RTC builds are experiencing an intermittent problem when the JBE begins Fetching files to fetch destination.
The build aborts.
The stack trace reports a 'Premature end of file'. 
The file in question is "Unknown"
When the build is re-run, the problem is gone and the build completes successfully.
