classloader plug point in ContextClassLoaderServiceDiscoverer

Hi

Along the same lines of  'ContributionClassLoader' discussion earlier, is
there a way to change or plug-in a different classloader to load registered
services which are under META-INF\services.
The reason for this is, the environment which tries to bootstrap Tuscany may
have different classloader structure compared to JSE env

Tuscany tries to load services using current thread's context classloader in
ContextClassLoaderServiceDiscoverer.ContextClassLoaderServiceDiscoverer()
and based on different environments classloader structure, current thread's
context classloader may not be able to load service registered under
META-INF\service leading to services
being null when Tuscany later tries to access them.

Is there a way to change or plug-in a different classloader in
ContextClassLoaderServiceDiscoverer.ContextClassLoaderServiceDiscoverer()

Regards
Rashmi
