We're getting null as result of IPackageFragmentRoot#getRawClasspathEntry().
*** Bug 182857 has been marked as a duplicate of this bug. ***
This indicates that the package fragment root is no longer on the classpath. We should throw a not present exception instead of returning null.
Created attachment 64934 [details] Proposed patch Not sure that message for the JME is the good one. Jerome, any advice on this point?
I code for the Java model status should not be INVALID_CLASSPATH (the classpath is still valid here) but ELEMENT_NOT_ON_CLASSPATH. So if the raw entry is null, we should: throw new JavaModelException(new JavaModelStatus(IJavaModelStatusConstants.ELEMENT_NOT_ON_CLASSPATH, this))
Created attachment 65008 [details] New proposed patch Thanks Jerome, here's the new patch including your recommended changes.
New patch looks good.
Released for 3.3 M7 in HEAD stream.
Verified for 3.3M7 with I20070427-0010
