RFR: 8337622: IllegalArgumentException in java.lang.reflect.Field.get [v2]

[Coleen Phillimore]

> Make the object init_lock be an injected field in the mirror so that reflecting on componentType will not inadvertently return the init_lock.  The init_lock is a Java object and the VM holds it during class linking and uses it to set state during class initialization.
> Tested with tier1-8.
