问题 My project was working fine yesterday. The only thing I did was to change the structure from a single war to a multi module pom. If I understand correctly the stacktrace there is ambiguousity between weld and omnifaces websocket lib. However there doesn't seem to be any call to any of my methods on the stacktrace.
