Summary: Inject protection_domain, signers, init_lock into java_lang_Class
Basic VM changes look fine to me.
Net footprint change is zero except that these fields are in Java heap rather than metaspace. This helps a little with InstanceKlass size which is in fixed size space with UseCompressedKlassPointers. Included serviceability because there were SA changes to code that I don't know is used.
Unsure about the SA changes. Basically you just removed access to the pd and signers, rather than changing it to allow access via the new path. That said I don't know SA so don't know whether it makes sense for SA to access things that are logically part of java.lang.Class; or whether it can access them more directly anyway because they are logically part of java.lang.Class.

Future work is to remove the signers field and the unused SetProtectionDomain function. open webrev at http://cr.openjdk.java.net/~coleenp/8003421/ bug link at http://bugs.sun.com/view_bug.do?bug_id=8003421 Tested with vm.quick.testlist, JPRT, jtreg java/security tests and jck8 tests. Thanks, Coleen
