Also test against java 15

[deivid-rodriguez]

I want to make sure things are fine on java 11 since that's the version I have installed locally.

[olleolleolle]

My .zshrc locally, needed

export JAVA_OPTS="$JAVA_OPTS --add-opens java.base/sun.nio.ch=ALL-UNNAMED --add-opens java.base/java.io=ALL-UNNAMED"

...perhaps we need such details, too?

[deivid-rodriguez]

The rake integration task is running into the classic java 11 specific error:

(OpenSSL::X509::StoreError) setting default path failed: No password supplied for PKCS#12 KeyStore.

Is that configuration to fix that?

[deivid-rodriguez]

Mmmmm, there are also some failures on the rake 11 job... I'll rerun to see whether they are flakies or not.

[deivid-rodriguez]

Alright, so rake 11 failed (might be flaky or not, not yet sure), and rake 10 is hanging, so... Let me propose my solution for everything: drop support for rake 10 and 11 😆. What do you think?

[olleolleolle]

@deivid-rodriguez Good, ambitious pace!

[deivid-rodriguez]

Flakies were independent from rake, they do seem related to the java version being used.

[deivid-rodriguez]

Funny we get these warnings on java 16:

WARN FilenoUtil : Native subprocess control requires open access to the JDK IO subsystem\nPass '--add-opens java.base/sun.nio.ch=ALL-UNNAMED --add-opens java.base/java.io=ALL-UNNAMED' to enable.\n

I'll add your suggestion.

[olleolleolle]

Oof java 8 complained https://github.com/jruby/warbler/runs/2801902936#step:4:19

  /home/runner/.rubies/jruby-9.2.18.0/bin/gem install bundler -v 1.17.3 --no-document
  Unrecognized option: --add-opens
  Error: Could not create the Java Virtual Machine.
  Error: A fatal exception has occurred. Program will exit.

[deivid-rodriguez]

Yeah, java 8 does not understand --add-opens. java 11 seems flaky somehow. And java 15 and 16 seem fine. Should we test against java 15 and 16?

[deivid-rodriguez]

I don't know why the options are not taking effect. It seems like the only java consistenty green is java 15. Should we just switch java 8 with java 15? My main motivation here is to get a local enviromnent that matches CI but I'd rather upgrade my java version that downgrade it to achieve that.

[deivid-rodriguez]

I went with my last proposal in the end.

[olleolleolle]

@deivid-rodriguez My friend was like "think of LTS"

https://www.oracle.com/java/technologies/java-se-support-roadmap.html

Release GA Date Premier Support Until Extended Support Until Sustaining Support
11 (LTS) September 2018 September 2023 September 2026 Indefinite (edited)

If you want to prune, I’d keep the LTS releases (8, 11 now and 17 in September) and only keep the latest non-LTS. So 16 right now.

But I lean towards "if 11 can't build, we don't have the bandwidth to fix that, now, toss it".

[deivid-rodriguez]

I see, maybe test on java 8 and 15 for now, and update that to 8 and 17, or maybe just 17 when it's released and we can make it pass?

[olleolleolle]

@deivid-rodriguez That sounds prudent, and will probably work!

I hope to create some more clarity around "what is the golden matrix we want to strive for".

[deivid-rodriguez]

I think the latest LTS and the latest non-LTS is a good goal. For now the second to last LTS, and the second to last non-LTS seems like a start :)
