Description DJ Houghton CLA 2010-12-03 08:41:42 EST 
Cloned bug to track release into R3.6.x stream.

+++ This bug was initially created as a clone of Bug #329385 +++

Build Identifier: 

Currently MetaDataRepository uses StringPool to intern shared strings.  However, the entry point is on XMLParser and results in each child repository of a CompositeRepository having its own copy of duplicate strings.

Additional savings can be gained by using the same StringPool to intern the strings for all child repositories.

Reproducible: Always

I will release this into 3.6.x but need to ensure that we coordinate the change with PDE/Build so their tests don't run out of permgen space.
