[Jython-bugs] [issue1116] parser NPE on dotted (more than 1) attribute decorators

[Philip J. <re...@bu...>]

New submission from Philip Jenvey <pj...@us...>:

A decorator with 1 dot parses ok:

@test_support.run_with_locale('LC_ALL', '')
def foo():
    print 'foo'

but NPEs with 2 dots:

@test.test_support.run_with_locale('LC_ALL', '')
def bar():
    print 'bar'

Traceback (most recent call last):
  (no code object) at line 0
java.lang.NullPointerException
