Description David Charboneau CLA 2004-10-07 15:53:41 EDT 
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.
Comment 2 Jerome Lanneluc CLA 2004-10-11 05:48:57 EDT 
Fix consists in using the packageFragments cache (instead of the
packageFragmentRoots cache) to lookup packages.
Comment 3 David Charboneau CLA 2004-10-11 09:23:59 EDT 
I have tested the proposed fix and seen a marked improvement in performance.
Comment 4 Philipe Mulet CLA 2005-01-26 15:54:24 EST 
Already released to maintenance branch.
