While deploying some services to a local DEV environment ( which is the prebuilt OTN SOA 12.1.3 VM ) using Maven Servicebus plugin, the deployment was failing for some reason. But instead of giving me the information about what is wrong with my service implementation, I received a NoClassDefFoundError. In the root cause of the exception stacktrace, it complains that class com/bea/wli/sb/util/DiagnosticLocation could not be found.
