Issue1656

jna invocations seem to sometimes break.  I'm not exactly sure what's going on, but the following Java code uses Waffle 1.3 and JNA 3.2.7.  It works fine from Java, but trying to invoke the static function from Jython throws an exception:

>>> import Demo
>>> Demo.main([])

You can grab the Waffle JARs here: http://waffle.codeplex.com/releases/view/43113

this looks like a bug in jna and waffle, unrelated to jython.  please close this while i follow up.

Closed per Vic's request.
