Description
WebSphere rejects all incoming SOAP messages to one-way WSDLs. This error does not occur on WebLogic.
OneWayProcessorInterceptor handleMessage throws a fault from line 93.
More specifically, org.apache.cxf.transport.AbstractConduit throws the exception from line 56.
This call to close gets us into org.apache.cxf.transport.http.AbstractHTTPDestination.flushHeaders(...) which calls IBM's implementation of SRTServletResponse.setContentType(...).
That implementation of setContentType(...) throws a NullPointerException when null is passed in.
