[Jython-users] Demo causes segfault.

[Dan W. <dcw...@ea...>]

I just intalled Jython on a RedHat 6.2 machine with jdk118_v1 from
Blackdown and I've run into some problems running the demos.  When I try
to run the demo in Demo/javaclasses I get a segfault.  Has anybody used
the blackdown jdk with Jython?  Is this a java version/vendor
compatiblity problem, or could be some kind of configuration problem?
