The serviceability libraries (as defined by jdk/make/lib/ServiceabilityLibraries.gmk) should be compiled with "warnings as errors". To enable this all current warnings need to be fixed.
The background for this is that we recently had a bug that could have easily been avoided if we had paid attention to the warnings.
