[castor-dev] StackOverflowError for circular references

[Srikanth Ganapavarapu]

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:documentation>
   </xsd:annotation>

 

   <xsd:element name="event">
      <xsd:annotation>
         <xsd:documentation>
             Event description information
         </xsd:documentation>
      </xsd:annotation>

 

      <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>
             The physical or virtual location of an event
         </xsd:documentation>
      </xsd:annotation>

 

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

 

   <xsd:element name="showTime">
      <xsd:annotation>
         <xsd:documentation>
             Show time information
         </xsd:documentation>
      </xsd:annotation>

 

      <xsd:complexType>
        <xsd:sequence>
            <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?
