Sun JAXB Accepts Message Despite Failure During Parsing

The Sun JAXB message silently drops errors during parsing.

This is related to the following issue: -

https://jira.jboss.org/jira/browse/JBPAPP-2114

The fix for JBPAPP-2114 corrects the parsing of the int '1-1' and results in a java.lang.NumberFormatException being thrown when this is parsed, JAXB subsequently drops this exception leaving the field set to it's default value of '0'.

We are using JAXB to use the default event handler which is supposed to reject errors and fatal errors: -

http://java.sun.com/javaee/5/docs/api/javax/xml/bind/Unmarshaller.html#setEventHandler%28javax.xml.bind.ValidationEventHandler%29

However JAXB is only stopping on fatal errors which is why this is not being picked.
