Description DJ Houghton CLA 2010-11-17 10:33:37 EST 
Cloned to track release into R3.6.x maintenance branch.

+++ This bug was initially created as a clone of Bug #329386 +++

Build Identifier: 

In certain (typical?) repositories such as the Helios repository manifest TouchPointData represents a significant contribution to memory footprint.  Since each manifest entry in the repository is unique string interning does not provide any savings.

Strategies for moving the manifests out of memory, or perhaps out of the repository in general need to be investigated and implemented.



Reproducible: Always

Touchpoint no longer reads manifest from touchpoint data

Here is a patch which changes the eclipse touchpoint so it no longer requires the full bundle manifest to exist in the touchpoint data. It retrieves its required properties from elsewhere in the IU.
