webrev: http://cr.openjdk.java.net/~ccheung/8200078/webrev.00/

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.
