It looks like jython use python 2.7 and as Unpacking Generalizations is a feature that introduced in python 3.5 you can not use this syntax in jython, so an alternative way to convert a tuple to a list is that use list ( match.groups) it works fine in older versions of python and current version of jython (2.7.2)
