Python new style classes contain a magic __basicsize__ attribute that 
returns the size of the object in bytes. Jython doesn't have this (and I 
don't see it having it any time soon or ever).
It's only referenced in one test, in test_descr, and has been commented 
out.
If we decide to never include it we should probably add the discrepancy 
to the old "Differences between CPython and Jython" document to close 
this issue out

this bug prevents test_descr.slotmultipleinheritance from passing (or is 
at least one of the reasons). the lack of it can probably be worked around 
for this test, though

test_descr.slotmultipleinheritance also relies on __weakref__, something
else we probably won't support

I suppose we could support java.lang.instrument.Instrumentation, however this does require a change in startup to run the instrumentation agent and is not likely to be available in a container.
I'm going to close this as "wont fix" given the problems we are likely to see. It really isn't a Java thing to do.
