Message4964

I can reliably reproduce this problem with the following set of tools:

Jython 2.5.0 release, Java 1.6.0_07-b06, django-jython svn rev 107,
Django 1.0.2-svn rev 9503 (from
http://code.djangoproject.com/svn/django/tags/releases/1.0.2/ - not the
1.0.x branch). This is on WinXP sp2.

Running the WAR command seems to intermittently generate corrupt
versions of settings$py.class, but I can't reproduce it consistently. 
Generating a new project *always* creates corrupt class files for me.
