Subject [jira] [Created] (SYNAPSE-1108) ProxyServiceMessageReceiver mediates message without default fault sequence

Joseph Caristi created SYNAPSE-1108:
---------------------------------------

             Summary: ProxyServiceMessageReceiver mediates message without default fault sequence
                 Key: SYNAPSE-1108
                 URL: https://issues.apache.org/jira/browse/SYNAPSE-1108
             Project: Synapse
          Issue Type: Bug
          Components: Core
    Affects Versions: 3.0.1
         Environment: WebLogic 12.2.1.3 war file
            Reporter: Joseph Caristi
            Assignee: Isuru Udana Loku Narangoda
             Fix For: FUTURE


With Synapse deployed as a war, we have defined the "main" and "fault" sequences in synapse.xml. 
The main sequence uses the xquery mediator to format a response.  If we introduce an error
in the xquery definition, the xquery mediator fails, but the default "fault" sequence is not
called.  This is because when the following code from ProxyServiceMessageReceiver executes,
the Synapse MessageContext fault stack is empty:
{code:java}
} else if (proxy.getTargetInLineInSequence() != null) {
 traceOrDebug(traceOn, "Using the anonymous " +
 "in-sequence of the proxy service for mediation");
 inSequenceResult = proxy.getTargetInLineInSequence().mediate(synCtx);
}{code}
 If we change the code to the following, it works:
 
{code:java}
} else if (proxy.getTargetInLineInSequence() != null) {
    traceOrDebug(traceOn, "Using the anonymous " +
        "in-sequence of the proxy service for mediation");     
    
    if (synCtx.getFaultStack().isEmpty()) {
        // set default fault handler
        synCtx.pushFaultHandler(new MediatorFaultHandler(synCtx.getFaultSequence()));
    }     inSequenceResult = proxy.getTargetInLineInSequence().mediate(synCtx);
}{code}
