RE: [p2-dev] root files 
OK, you may be affected by the same bug I was
(https://bugs.eclipse.org/bugs/show_bug.cgi?id=277768).  Are you by any
chance defining 'customBuildCallbacks' in your build.properties as well?
This appears to hose the default behavior and generates a feature JAR IU
for root-file-only features when it shouldn't.

Mark.
