I also checked the classfile of org.eclipse.jetty.xml.XMLConfiguration , it seems deprecated .

How did you do this upgrade? It looks like an older jetty-util is being used.

Sounds like a bug to report or discuss with the devs on their mailing list, if so.

Hi,
Issue is resolved now , It was actually taking jetty jars from two of the classpath one is open jdk and the other is jetty classpath , hence at runtime it was confused which version of jetty util , jetty xml to be picked and was resulting in InvocationTargetException. Somehow older version of jetty util and jetty xmls were available in my jdk lib folder . Removing those fixed the errors.

Thanks
