Robert Muir commented on LUCENE-9235:
-------------------------------------
So its the original code that's wrong. It relies on undefined dictionary order.
Now the generation code behaves crazy depending on your version of python.
Since I have python3.6+, the ordering of dictionaries becomes well-defined
(insertion order). So I can run 'ant regenerate' a million times on my computer
and generated code will not change.
But if you have an older python version, you'll probably see diffs in generated
output because it will use arbitrary order.
> upgrade all python to python3

> Lets just kill the python2 and simplify the build. Since its only being used
