NPE and classcast exceptions when putting all SCA jars from libs and modules on
classpath
-----------------------------------------------------------------------------------------
Key: TUSCANY-1941
URL: https://issues.apache.org/jira/browse/TUSCANY-1941
Project: Tuscany
Issue Type: Bug
Components: Java SCA Axis Binding Extension
Affects Versions: Java-SCA-1.0.1
Environment: windows, jdk1.6.0_02
Reporter: andrej koelewijn
Priority: Trivial
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.
Stacktrace for cli application:

Problem can be solved by only including tuscany-sca-manifest.jar on the
classpath, or by removing all jars in modules from the classpath.
