             Summary: ArrayIndexOutOfBoundsException in BeanUtil.deserialize()
                 Key: AXIS2-5426
                 URL: https://issues.apache.org/jira/browse/AXIS2-5426
             Project: Axis2
          Issue Type: Bug
          Components: adb
    Affects Versions: 1.6.2
            Reporter: Robert Jäschke


Using Axis2 I have created Java stubs for the Amazon Mechanical Turk WSDL and implemented the server and client side. Now upon receiving a SOAP message, I get an ArrayIndexOutOfBoundsException on the server side:

[2012-09-19 17:26:32,907] [DEBUG] [org.apache.axis2.client.Options] - setAction Old action is (null)

This happens at this code position in BeanUtil.deserialize():

       while ((parameterNames != null) &&
                   (!omElement.getQName().getLocalPart().startsWith("arg")) &&
                   (!omElement.getQName().getLocalPart().startsWith("item")) &&
                   !omElement.getQName().getLocalPart().equals(parameterNames[count])) {
                // POJO handles OMElement in a differnt way so need this check for OMElement
                Class paramClassType = (Class) javaTypes[count];
                if (!paramClassType.getName().equals(OMElement.class.getName())) {
                    count++;
                } else {
                    break;
                }
            }

The access to parameterNames[count] in the while loop is causing the ArrayIndexOutOfBoundsException because count is increased beyond the array's size in the following if statement. In my case the value of paramClassType is "com.amazonaws.mturk.requester.doc._2012_03_25.CreateHIT" and not "org.apache.axiom.om.OMElement" and hence the check fails.

Is this an error in Axis2 or am I doing something wrong? Actually, I have not modified the generated code (it's automatically re-generated by Maven anyway) so I would expect that I can't do anything wrong to this respect.


(To be honest, I had to change something: I am doing

client._getServiceClient().getOptions().setProperty(org.apache.axis2.Constants.Configuration.DISABLE_SOAP_ACTION, org.apache.axis2.Constants.VALUE_TRUE);

because otherwise the client sends a SOAPAction HTTP header with the value "http://soap.amazon.com/" which causes the server not to find the action. My setup is "weird" in the sense that I am not just programming the client that shall work against Amazon Mechanical Turk but I have also implemented the server side myself and thus I am using http://localhost:4321/axis/services/amt as endpoint and not amazon.com.)
