> When xalan.jar is not on the classpath, then {{org.apache.activemq.filter.XalanXPathEvaluator}} in {{evaluate()}} method tries to load {{org.apache.xpath.CachedXPathAPI}}, throws {{NoClassDefFoundError}}, that is catched as {{Throwable}} and {{false}} is returned instead of an error.
> No clue is given to the client, that it lacks a jar on the classpath and the impression is, that XPath selectors doesn't work and return false whatever the message is.
> I believe if we catch {{Exception}} instead of {{Throwable}}, then the problem would be fixed.
