Scott Kurz commented on TUSCANY-3681:
-------------------------------------
I see. So Simon, you're referring to the specification of:
org.oasisopen.sca.client.SCAClientFactory.getService(Class<T> interfaze,
String serviceURI)
So I'm not sure where this matter stands in 2.x, but in any case I'm still not
sure we would expect this to work in 1.x. Would we?
Note that an alternative bypassing this problem would be to insert a component
between the client and the service exposed over binding.jms. This intermediate
component could be configured with a reference with binding.jms, and in turn
accessed by the client via a getService() call, (the intermediate component
service being exposed over the default binding).

> Reporter: Sebastian Millies

>
> I call a service method exposed by a JMS binding. However, at the time when
> the constructor of
> org.apache.tuscany.sca.binding.jms.wireformat.jmsdefault.runtim.WireFormatJMSDefaultReferenceInterceptor
> is executed, the inputWrapperMap argument is empty (size 0), which leads to a
> NullPointerException later on when the requestMsg is constructed in method
> invokeRequest.
> The stack trace is this:
> java.lang.NullPointerException
