[nstdio]

Update Java baseline version to 17.

I can help with this if you want.

Thanks for all your work! do you have some estimation about when to release this update?

[nstdio]

To be frank, I didn't put a lot of thought in this issue. I'm bit tentative about raising baseline to 17, because rsql-parser is really simple library and it is not entirely clear to me how it can leverage from Java 17.

Can you please share your case?
