Description Dean Roberts CLA 2011-12-06 13:27:03 EST 
This happened when trying to import a project into a a brand new, unaltered Eclipse during testing.  

Build ID: I20111205-2330

The resulting import also happens to report build path problems due to missing JREs ... which is likely true, however, Manifest Builder should probably not be throwing NPEs to the log.

Steps to reproduce:

1) Use File->Import->General->Existing Projects into Workspace to import the projects attached to this defect.

2) Note the error in the error log:

Comment 1 Dean Roberts CLA 2011-12-06 13:27:47 EST 
These are the two warnings I get in the problems view.  The warnings are likely valid

Description	Resource	Path	Location	Type
Build path specifies execution environment J2SE-1.5. There are no JREs installed in the workspace that are strictly compatible with this environment. 	activity		Build path	JRE System Library Problem
