Description Thomas Watson CLA 2010-09-20 08:44:12 EDT 
+++ This bug was initially created as a clone of Bug #272087 +++

N20090412

Profiling startup of a simple headless application, there is a significant hit in the ds activator due to computation of localized manifest data. It looks like we can make an optimization similar to bug 271621 to avoid this computatation (use getHeaders("") instead of getHeaders(). The two invocations of getHeaders() in ds activation cost 8% of the total startup time.

See Activator.start line 157 and SCRManager.startedBundle line 477.

Opening this bug to release to 3.4.2+ stream.  See patch on bug272087
