OldObjectSample event causing bloat in the class constant pool in JFR recording

        Allocation heavy applications with OldObjectSample enabled will end up storing many duplicates of the same klass artifact, creating a huge bloat in the class area of the recording constant pool (see the akka_6.jfr.zip attachment).

        While this is just annoying when the recording does not have the max size set it becomes a real problem with max size - the class constant pool will push out the useful data eventually (again, see the akka_6.jfr.zip attachment).
