No, I didn't include org.sax in the webapp.

The TempClassLoader loads ch.qos.logback.classic.LoggerContext which 
uses SAXParser,parse(), so the TempClassLoader also loads the argument 
types for this method, including org.xml.sax.helpers.DefaultHandler.

org.xml does not belong to the skip prefixes defined in TempClassLoader, 
thus the TempClassLoader loads DefaultHandler by itself, i.e. not by the 
same class loader that loaded SAXParser.

This is what causes the conflict. I don't think there's anything I can 
do about it at webapp level.

Best regards,
