> Reporter: afuqua
> Assignee: Michael Glavassevich
> Fix For: 2.9.1

> On Windows XP and NT and 2000, when validating a document with the schema
> below, I get a stackOverflow. I've seen the overflow report in 2 different
> locations for different schemas:
> java.lang.StackOverflowError
> at org.apache.xerces.impl.xs.models.XSDFACM.postTreeBuildInit
> (XSDFACM.java:899)
> ....
> java.lang.StackOverflowError
> at org.apache.xerces.impl.xs.models.XSDFACM.calcFollowList
> (XSDFACM.java:732)
> ....
> Here's an example schema to reproduce the problem:
> <?xml version="1.0" encoding="UTF-8"?>
> <schema xmlns="http://www.w3.org/2001/XMLSchema"
> targetNamespace="http://www.iss.net/cpe/stackOverflow"
> xmlns:stackOverflow="http://www.iss.net/cpe/stackOverflow"
> elementFormDefault="qualified"
> attributeFormDefault="unqualified">
>
> <element name="policy" type="stackOverflow:PolicyType"/>
> <complexType name="PolicyType">
> <sequence>
> <!-- fails for me as low as 5000 and up -->
> <element name='sensitivity'
> type='stackOverflow:sensitivityType' minOccurs='0' maxOccurs='65535'/>
> </sequence>
> </complexType>
>
> <complexType name="sensitivityType">
> <attribute name="sensitivity" type="int" use="required"/>
> </complexType>
> </schema>
> Here's a code excerpt:
> DOMParser domParser = new DOMParser();
> domParser.setErrorHandler( errorHandler );
> domParser.setFeature( "http://xml.org/sax/features/namespaces", true );
> domParser.setFeature( "http://apache.org/xml/features/validation/schema",
> true );
> domParser.setFeature( "http://xml.org/sax/features/validation", true );
> domParser.setProperty( "http://apache.org/xml/properties/schema/external-
> schemaLocation", ....);
> domParser.parse( new InputSource( new StringReader( .... )) );
