Buggy source:
public void handle(ExceptionMessage muleMsg){
  try {
    Object requestMsg=muleMsg.getPayload();
    String requestString=requestMsg.toString();
    BaseMessage msg=(BaseMessage)BindingManager.getBinding("String_Node_Str").fromOM(requestString);
    Throwable ex=muleMsg.getException().getCause();
    StorageErrorMessageType errMsg=null;
    if (ex instanceof NoSuchVolumeException) {
      errMsg=new StorageErrorMessageType("String_Node_Str","String_Node_Str",HttpStatus.SC_NOT_FOUND,msg.getCorrelationId());
      errMsg.setCorrelationId(msg.getCorrelationId());
    }

Fixed version (ground truth):

    if (ex instanceof NoSuchVolumeException) {
      errMsg=new StorageErrorMessageType("String_Node_Str","String_Node_Str",HttpStatus.SC_NOT_FOUND,msg.getCorrelationId());
      errMsg.setCorrelationId(msg.getCorrelationId());
    }
 else     if (ex instanceof VolumeInUseException) {
      errMsg=new StorageErrorMessageType("String_Node_Str","String_Node_Str",HttpStatus.SC_FORBIDDEN,msg.getCorrelationId());
      errMsg.setCorrelationId(msg.getCorrelationId());
    }
