Log:
OWB-414 drop doPrivileged from ClassLoader detection
retrieving the CurrentContextClassLoader via SecurityManager
is a highly expensive task. Doing this in the most heavy spot
of OWB means a measured performance penalty from 20 to 30%.
Given the fact that OWB (even if running in Geronimo or any
other multi ClassLoader scenario) will always get bootstrapped
in the context of a WebApp, we should not get any problems
by dropping it.
