Re: [Jython-users] Java 17 and support for jython

[Jeff A. <ja...@fa...>]

Jython 2 is built with Java 8 and tested with Java 8 and Java 11.

The backwards compatibility of Java versions is very high. The byte code 
is stable. What varies slightly is the Java API, where methods may have 
been removed, or others overloaded in ways that affect exactly which is 
found during a call.

I ran the regression tests on an installed 2.7.3 with Java 17. The 
expected result is explained here:

https://jython-devguide.readthedocs.io/en/latest/release_jy.html#installation-regrtest

With Java 17 I got an additional failure from test_httplib that is to do 
with header data not expected by the test. That may well be satisfactory 
for your application. You'll do your own tests, of course, and can 
repeat ours fairly easily.

There may be a 2.7.4 this year, and it may be tested with Java 17, but 
an eventual Jython 3 will get most of the time.
