Hey,

We are trying to use the below .xsd file content with Castor 0.9.3.
If you observe there exists some circular references among "event",
"location" and "showTime".


<?xml version="1.0"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";
  targetNamespace="http://castor.exolab.org/Test/Invoice";>

   <xsd:annotation>
      <xsd:documentation>
         This is a reference XML Schema to compare against the generated
         schema from the event mapping xml file.

   </xsd:annotation>

   <xsd:element name="event">
      <xsd:annotation>
         <xsd:documentation>

      <xsd:complexType>
        <xsd:sequence>
            <xsd:element name="id" type="xsd:long"/>
            <xsd:element name="name" type="xsd:string"/>
            <xsd:element ref="showTime" maxOccurs="unbounded" minOccurs="1"/>
            <xsd:element ref="location" maxOccurs="unbounded" minOccurs="1"/>
       </xsd:sequence>
      </xsd:complexType>
   </xsd:element>

   <xsd:element name="location">
      <xsd:annotation>
         <xsd:documentation>

         </xsd:documentation>

            <xsd:element name="id" type="xsd:long"/>

            <xsd:element ref="event" maxOccurs="unbounded" minOccurs="1"/>
       </xsd:sequence>
      </xsd:complexType>
   </xsd:element>

   <xsd:element name="showTime">

            <xsd:element name="id" type="xsd:long"/>
            <xsd:element name="startTime" type="xsd:dateTime"/>
            <xsd:element name="endTime" type="xsd:dateTime"/>
            <xsd:element ref="location"/>
            <xsd:element ref="event"/>
       </xsd:sequence>
      </xsd:complexType>
   </xsd:element>

</xsd:schema>


We expect castor to process this. But it is resulting in a
java.lang.StackOverflowError and terminating.

Does anyone know anything about this?
