It's not documented to do so, and as Charles said, it would be a huge
incompatibility.

It isn't - it's been OCO for a long time. But it has evidently changed in 2.2.

That's right - "any" generally doesn't include above the bar. But some
OCO control blocks have been moved above the bar.

There isn't one. Peter Relson warned of these changes back in June
(but with no details).
I think you are stuck with a JNI routine. But that doesn't address the
problem of doing these conversions when processing a dump. It's not
obvious that the SWAREQ etc. processing will work on addresses not
from the running system.
