7173959: Jvm crashed during coherence exabus (tmb) testing Summary: Mapping of aligned memory needs to be MT safe. Also reviewed by: vitalyd@gmail.com Reviewed-by: dholmes, coleenp, zgu

8001028: Improve GC option handling Summary: If there are not enough native resources to create the ReferenceHandler or Finalizer Java threads, the VM will attempt to throw an OOME before the java.lang.Class class has been initialized. This can result in assertion failures and other crashes. Move the initialization of the java.lang.Class class to just before the initialization of the java.lang.ref.Finalizer class.
