I got the same error. However, when investigating it a bit
further I saw that the python_21.class was actually a html file.

When one use "save as" for the download link, that is what
happens. The html file is saved. One gets fooled doing so,
since the browser wants to launch the class as an applet.

Is there any reason to leave this open since the installer
is now a jar file?  This will probably keep browsers from
downloading it as a html file.

You are right - there is no reason.
Thanks!
