The problem still exists in 2.5a2.

I wrote a small python script to remove the 55 duplicates files from
jython_installer-2.5a2\jython-complete.jar:
org/python/core/PyArray.class

Afterwards I could at least start the "real" installation process which
immediately ended with an Exception:

Exception in thread "main" java.lang.NoClassDefFoundError:
org/python/util/install/Installation
Caused by: java.lang.ClassNotFoundException:
org.python.util.install.Installation

The org.python.util directory even has no subfolders.
