The Event Based tracing framework assigns a unique traceid to Klass:es for tracking purposes.

Normally, a new Klass is assigned its trace_id in the Klass constructor.

See https://bugs.openjdk.java.net/browse/JDK-8012714 

For Klass:es coming into the system via the ClassDataSharing (CDS) mechanism, the old trace_id for the Klass will be stale, hence a "new" trace_id needs to be (re)assigned to the Klass.
Fix in progress.
