Platform BZ for https://issues.jboss.org/browse/JBWS-3682

Anonymous types (annotated with @XmlType(name = "")) in an exception class aren't generated at all in WSDL.

Web service classes:
--------------------
@WebService
public class GreetingService {
  @WebMethod
  public void hello() throws MyException {}
  ...

public class MyException extends Exception {
  private String     str;
  private MyAnonType myAnonObj;

  public String getStr() { return str; }
  public void setStr(String str) { this.str = str; }

  public MyAnonType getMyAnonObj() { return myAnonObj; }
  public void setMyAnonObj(MyAnonType myAnonObj) { this.myAnonObj = myAnonObj; }
  ...

@XmlType(name = "")
public class MyAnonType { ...

Generated WSDL:
---------------
  <wsdl:types>
<xs:schema ...>
  ...
  <xs:complexType name="MyException">
    <xs:sequence>
      <xs:element name="str" nillable="true" type="xs:string"/>
    </xs:sequence>
  </xs:complexType>

Note that the same type (MyAnonType) is generated in WSDL if the @XmlType(name = "") annotation is removed.
