Rajini Sivaram updated TUSCANY-1941:
------------------------------------
Attachment: ReallySmallRuntime-patch.txt
Attached patch loads each module (as determined by the classname inside
META-INF/services/org.apache.tuscany.sca.core.ModuleActivator) and runs its
module activator only once, even if multiple versions of these modules are on
the CLASSPATH..
> NPE and classcast exceptions when putting all SCA jars from libs and modules

> When i put all jars from the libs and modules directories on my classpath
> (modules first, then libs), i get a nullpointer exception (when running
> standalone), or a classcast exception (when running as part of a webapp). In
> both stacktraces i can see that it's using axion in the axis2 binding code.
