Summary: exceptions problem in __str__

Initial Comment:
When defining a class that overloads the __str__ 
method and raises an exception in the overloaded 
method, for example

class C:
  def __str__(self):
    raise Exception("i am an exception")

If we call str on an object of this class the exception will 
not be raised

x=C()
str(x)

(no exception will be reported by jython)

P.S.
when using x.__str__() the exception will be raised and 
jython will display it

The behaviour of raising an exception is consistent with CPython.  The 
bug is in PyInstance which catches the thrown exception and then calls 
__repr__.
