# There's a bug in the jpython pattern matching.
# The pattern element '+?' is broken.  See below
# for a demo of how it's broken.  I've tested the
# same program in CPython and verified that the
# problem does not occur there.
#
# Using jython 2.1 on OS-X 10.2, the following program
# demonstrates the problem, by printing the following:
#
#       Matching pattern, r'\w+:', against string, 'my, test; data:',
#           no match (correct).
#       Matching pattern, r'\w+?:', against string, 'my, test; data:',
#           matched...  mobj.group()="my, test; data:" (incorrect).
