Insufficient optimisation in JBossXSModel traversing XML schema
---------------------------------------------------------------

                 Key: JBWS-2638
                 URL: https://jira.jboss.org/jira/browse/JBWS-2638
             Project: JBoss Web Services
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: jbossws-native
    Affects Versions:  jbossws-native-3.1.1
            Reporter: Darran Lofthouse
            Assignee: Darran Lofthouse
             Fix For:  jbossws-native-3.1.2


The JBossXSModel implementation requires further optimisation to reduce deployment overhead for complex schemas.

Take the following type: -

  <xs:complexType abstract='true' name='cmisBaseType'>
   <xs:sequence>
    <xs:choice maxOccurs='unbounded' minOccurs='0'>
     <xs:element ref='tns:base'/>
     <xs:element ref='tns:baseDateTime'/>
     <xs:element ref='tns:baseBoolean'/>
     <xs:element ref='tns:baseHtml'/>
     <xs:element ref='tns:baseInteger'/>
     <xs:element ref='tns:baseDecimal'/>
     <xs:element ref='tns:baseString'/>
     <xs:element ref='tns:baseId'/>
     <xs:element ref='tns:baseUri'/>
     <xs:element ref='tns:baseXml'/>
    </xs:choice>
   </xs:sequence>
  </xs:complexType>

If each of the element types referenced here extend this type then there are many routes to reach each type.  The class JBossXSModel does detect cyclic references but it does not detect if a type has already been processed if re-visit in a non cyclic way.

This Jira issue it to modify the current optimisation to detect second visits to a type by any route.
