That is no longer the case. A condition was added to make sure we still get non-immediate oops on AArch64 for collectors that use nmethod entry barriers, and support immediate oops. However, the condition was messed up, so we instead end up doing the wrong thing. We should do the right thing.

Looks good to me too.
