Seems something on the classpath is trying to set this option: -XmessageHandlerClass and it is passing kamon.weaver.logging.KamonWeaverMessageHandler
which cannot be cast to an AspectJ IMessageHandler. Is it your code doing that or an aop.xml from some other jar in the system? To get going you could turn off whatever is trying to set that option (modify aop.xml) cheers, Andy On 4 August 2014 12:22, Ivan Topolnjak <[email protected]> wrote: > Hello there, I have been trying
