-------------------------------------

             Summary: StackOverflowError when parsing a large number of characters in \
an XML element  Key: XMLBEANS-495
                 URL: https://issues.apache.org/jira/browse/XMLBEANS-495
             Project: XMLBeans
          Issue Type: Bug
          Components: Validator
    Affects Versions: Version 2.6
         Environment: All
            Reporter: Mandy Warren


When XMLBeans validates a very long XML String (1000 or more chars), it generates a \
StackOverFlowException as shown below. In the schema for this element I have defined \
a pattern and a min/max length but XMLBeans is applying the pattern first before \
checking the length. The solution is the fix applied to the class RegularExpression \
in xerces - see https://issues.apache.org/jira/browse/XERCESJ-589 which went into \
version 2.11. 

	<xs:simpleType name="info">
		<xs:restriction base="xs:string">
			<xs:maxLength value="3"/>
			<xs:minLength value="2"/>
			<xs:pattern value="[A-Z0-9]+"/>
		</xs:restriction>
	</xs:simpleType>
