---------------------------------------

Aleksey, Is it better to move this caching to class creation/preparation in native?

> Serialization workloads relies on Class.isAssignableFrom(...) when looking up Serializable and Externalizable properties (that is, implementation of interfaces). For now, DRLVM kernel classes perform lookups on each invocation. This issue caches the mentioned properties in Class fields and does not go to native VMClassRegistry for resolution.
