OK.  I'm going to step through to see if that is what really happens.
I'm pretty sure that when I did step through I didn't see any NULLing
of the klass field, but I take it from your answer that the only time
this actually needs to happen is when an object is allocated by the
C++ runtime code, not by the JIT-generated code or the JIT's runtime
libraries, which only ever allocated in the young gen.
