Why does Grails need Xerces?

Question

We had in a grails-project problems with different XML-libraries clashing. The solution was to delete xercesImpl.jar from $GRAILS_HOME/lib. Grails does work well without it. So my question is, why was the xerces-library in the grails-distribution in the first place?

Answer 1

A common reason for including an XML parser is if the application needs to run on earlier JRE versions.
