it's glitch in how java method are dispatched, in disambiguating the 
unbound method
from the static one. What you are getting is the behavior of 
java.lang.Object.toString

We can do better in most cases, and there's a bug in the tracker to remind 
about this, can't say right now whether things will improve for 2.2 or after.
