Sometimes this happens:

Caused by: java.lang.NullPointerException: Cannot invoke "org.eclipse.core.runtime.IPath.toFile()" because the return value of "org.eclipse.core.resources.IFile.getLocation()" is null

I can provide a pull request, but I'm not sure what's the solution.

Do you manage to reproduce it deterministically (so that one can debug it)?
