[jira] [Updated] (XMLBEANS-495) StackOverflowError when parsing a
large number of characters in an XML element
[ https://issues.apache.org/jira/browse/XMLBEANS-495?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Mandy Warren updated XMLBEANS-495:
----------------------------------
Description:
When XMLBeans validates a very long XML String (4000 or so chars), it generates a StackOverFlowError 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>
Exception in thread "main" java.lang.StackOverflowError
