com.sun.management.ThreadMXBean (and other platform MXBeans) is a
"sealed" interface which should only be implemented by JDK.
Unfortunately we don't have the sealed type feature yet. Yes it needs
to be a default method. I think it should throw UOE.

UnsupportedOperationException}.
The @throw UOE can make it clear that it does not support current thread
memory allocation measurement.
