> Get rid of WeakReference-based logic in > DirectMethodHandle::checkInitialized() and reimplement it with > `Unsafe::ensureClassInitialized()`/`shouldBeInitialized()`. > > The key observation is that `Unsafe::ensureClassInitialized()` does not block > the initializing thread. > > Also, removed `Unsafe::shouldBeInitialized()` in > `DMH::shouldBeInitialized(MemberName)` to save on calling into the VM. > `Unsafe::ensureClassInitialized()` already has a fast-path check which checks > whether the class is fully initialized or not. > > Testing: tier1 - tier6
