Right, unless there is a way to inject them conditionally.

But if you move these fields into Class.java (in JDK8), then hsx25

It seems like you could take this opportunity to make these declared

allowing, for example, getProtectionDomain0() to be a simple Java

Summary: Inject protection_domain, signers, init_lock into
java_lang_Class
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.
Future work is to remove the signers field and the unused
SetProtectionDomain function.
