Issue625364

When an exception is raised in jython, 
sys.last_traceback  doesn't seem to 
 get, and sys.exc_info() returns (None, None, None).
 sys.exc_info() only seems to return something while in 
a catch block, i.e.
 
 try:
         raise 'hello'
 except:
         print sys.last_traceback
         print sys.exc_info()
 
 None
 ('hello', None, <traceback object at 18669924>)
 
 
 raise 'hello'
 Traceback (innermost last):
   File "<console>", line 1, in ?
 hello
 print sys.last_traceback
 None
 print sys.exc_info()
 (None, None, None).
 
 Is this intentional?
 If so, how do I get the pdb postmortem facility to 
work - it tries to 
 access sys.last_traceback

it's a bug, in InteractiveIntepreter I think, it uses toString 
instead of
 Py.printException, where the logic for setting last_* is.
 Btw that logic does not seem to be threadsafe if 
PySystemState instance is
 shared. Honestly is the first time I look at that code and I 
presume nobody has
 used it so far :(.

Fixed in InteractiveInterpreter.java: 2.9;
