Instead of SomeInterface.class.getName() you should either
SomeInterface.getName(), SomeInterface.__name__ (perhaps more
Pythonic), SomeInterface.class.getName(SomeInterface) or
SomeInterface.class.__name__. At least those work with
java.lang.Runnable interface as shown below.

Jython 2.2b1 on java1.5.0_10 (JIT: null)
Type "copyright", "credits" or "license" for more information.
>>> from java.lang import Runnable
>>> Runnable.getName()
'java.lang.Runnable'
>>> Runnable.__name__
'java.lang.Runnable'
>>> Runnable.class.getName()
Traceback (innermost last):
  File "<console>", line 1, in ?
TypeError: getName(): expected 1 args; got 0
>>> Runnable.class.getName(Runnable)
'java.lang.Runnable'
>>> Runnable.class.__name__
'java.lang.Class'
>>>
