> 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.
