> I'm seeing an NPE thrown by PassByValueInterceptor in the greeterws-oneway sample, service side. The trace is below. This happens after the invocation of the service returns (with a null, since it is a void return type). The target invoker puts the null return value in the message body and returns the message. The interceptor then gets the body and tries to do something with it. My thought then was that the supplychain sample should also fail, but it does not, not sure why, perhaps the interceptor is not used there. Notice that the databinding interceptor does check to see if the operation is non-blocking (ie, one-way) before it tries to do something with the result, but in that case the interceptor returns immediately and does not do any more transformation. Not sure what the correct behavior for the pass-by-value interceptor should be here.
