Description

Hi there,

I just did and upgrade from Axis2 1.6.2 to Axis2 1.8.2.

And unfortunately it looks like there's a new bug with the empty tags for enums and axis returns the following error:

processAxisFault() found a null HTTP status from the MessageContext instance, setting HttpServletResponse status to: axis2.http.response.state

from this method: https://github.com/apache/axis-axis2-java-core/blob/a8fd43c2aa8a03739cced810842af12ff3ad293d/modules/transport/http/src/main/java/org/apache/axis2/transport/http/AxisServlet.java#L409

wsdl definition:

<wsdl:message name="getUserEventRequest">
    <wsdl:part name="userEventQuery" type="types:SomeEventFilter"></wsdl:part>
  </wsdl:message>

This is an example of the xsd:

<xs:complexType name="SomeEventFilter">
    <xs:sequence>
      <xs:element minOccurs="0" maxOccurs="1" name="userName" type="xs:string"/>
      <xs:element minOccurs="0" maxOccurs="1" name="eventType" type="SomeEvent"/>
    </xs:sequence>
  </xs:complexType>

  <xs:simpleType name="SomeEvent">
    <xs:restriction base="xs:string">
      <xs:enumeration value="ACTION1"/>
      <xs:enumeration value="ACTION2"/>
      <xs:enumeration value="ACTION3"/>
    </xs:restriction>
  </xs:simpleType>

And this is the response:

<soapenv:Fault> 
 <faultcode>soapenv:Server</faultcode> 
 <faultstring>unknown</faultstring> 
 <detail/> 
</soapenv:Fault>

I know for sure that the same wsdl works on Axis2 1.6.2 because I already tested the same request and works fine.

If you have any insights on this issue, I'll appreciate!
