When running jython with -Qnew, it always errors out.
Looks like there should be a break after new in the switch case to prevent the -Q option from falling through to the default failure

I thought I'd be familiar with Java and Jython, but I never heard of the "-Q" option. It does not seem to be a Java option:
https://docs.oracle.com/en/java/javase/14/docs/specs/man/java.html
And not a Jython option:
https://github.com/jythontools/jython/blob/b9ff520f4f65231209d5200c22724516a72e75f2/src/shell/jython.py#L399
https://www.jython.org/registry
I suppose it is not referring to the quiet-flag:
-q: don't print version and copyright messages on interactive startup
So, what is it? Could you link a specification?
And provide some more context. Is it a launch option?

Okay, Python 2 specific division option. (Had looked up Python 3 usage)
-Q arg: division options: -Qold (default), -Qwarn, -Qwarnall, -Qnew

Sorry, schoolboy error, and evidently no test to fail. Easy fix (once we are on GitHub).
