Not fixed, and very odd, considering where it happens.

Normally with the message "Cannot create PyString with non-byte value" I'd suspect non-ascii paths or character coding on the host, but I think the string here should just be a class name. It's going wrong here:

https://github.com/jythontools/jython/blob/v2.7.2/src/org/python/core/PyJavaType.java#L543

and I wonder why Jython is doing stuff with reflected methods anyway? And why only on your machine?

It's not like installing on a Windows machine is anything new, and I don't see why this bit should be sensitive to anything in your particular environment. It looks like code that would execute identically whenever Jython starts on any machine.

Could the installer be a bad copy? You'd think it wouldn't run at all, in that case, but I'm stumped for now.
