NameLookup.seekPackageFragments has regressed from Eclipse 2.0. This method is
used heavily by JDOM and JEM, which are in turn used heavily by EJB Validation
in IBM Rational Application Developer.

Reviewed proposed change. Looks good.
Ok to release in maintenance stream.

Fix consists in using the packageFragments cache (instead of the
packageFragmentRoots cache) to lookup packages.
