[switchyard-issues] [JBoss JIRA] (SWITCHYARD-568) SOAP gateway throws NPE when processing GET

[Keith Babo (Created) (JIRA)]

SOAP gateway throws NPE when processing GET
-------------------------------------------

                 Key: SWITCHYARD-568
                 URL: https://issues.jboss.org/browse/SWITCHYARD-568
             Project: SwitchYard
          Issue Type: Bug
          Components: component-soap
            Reporter: Keith Babo
             Fix For: 0.4


Deploy an app with a SOAP gateway binding and then put the endpoint URL in your browser.  See below for the output.  We need to detect GETs *empty* POST payloads and deal with them in a more graceful manner.  Running into this is quite common when people browse for the ?wsdl of a SOAP endpoint.
