Description Kevin O'Neill CLA 2002-12-30 00:46:04 EST 
If you create a custom IClassPathEntry class then
JavaProject.computePackageFragmentRoots throws an exception when the
IClassPathEntry passed to the method is cast to the internal ClasspathEntry
 
String rootID = ((ClasspathEntry)resolvedEntry).rootID();

My work around is to create an instance of ClasspathEntry rather than my custom
IClasspathEntry. This is not 100% legit as the ClasspathEntry class is in an
internal package.

From IClasspathEntry javadoc:

 * This interface is not intended to be implemented by clients.
 * Classpath entries can be created via methods on <code>JavaCore</code>.

Closing, working as designed.
