>> During CDS dumping, when a class fails to load due to OOM (insufficient metaspace), GC tries to free the class which will in turn frees its _transitive_interfaces. But if the _transitive_interfaces is being shared with another class which has been loaded successfully, it will result in vm crash.
>> The change is to stop CDS dumping right away when an OOM due to insufficient metaspace is encountered.
