[Jython-users] bug in traceback module?

[Carl K. <cmk...@gm...>]

Here is a minimal textcase to show the problem:

Jython(2.1 as well as 2.2alpha) does not show the outermost
frame from within an exception occurs:

# - exc_test.py -
import sys,traceback
def a(): print 1 + "1"
if __name__ == '__main__':
    try: a()
    except: t,v,tr = sys.exc_info(); traceback.print_exception(t,v,tr)


>python exc_test.py 
Traceback (most recent call last):
  File "exc_test.py", line 4, in ?
    try: a()
  File "exc_test.py", line 2, in a
    def a(): print 1 + "1"
TypeError: unsupported operand types for +: 'int' and 'str'


>jython exc_test.py 
Traceback (most recent call last):
  File "exc_test.py", line 2, in a
    def a(): print 1 + "1"
TypeError: __add__ nor __radd__ defined for these operands


Is there a way to get around this? I really want to see both frames:
  File "exc_test.py", line 4, in ?
    try: a()
  File "exc_test.py", line 2, in a
    def a(): print 1 + "1"

Regards

Carl
