test Travis-CI on JDK 17

[SethTisue]

Travis-CI is failing because SDKMAN isn't finding JDK 17 anymore.

Not sure what changed. Is scala/scala-dev@1a7c0e6 not right anymore?

[SethTisue]

scala/scala-dev@47118f1#diff-f4dff8443b496634d47500e60fd050b98480f2ee7b16635c2d5c43d131a9c398 gives us additional debugging output

and now at https://app.travis-ci.com/github/scala/scala-xml/jobs/536511441 we see that the only Java.net build of 17 available is 17.ea.3.pma; there used to also be 17.ea.28

also confirmed by this by running sdk list java locally on my Mac and I see:

               | >>> | 17.ea.28     | open    | local only | 17.ea.28-open       
               |     | 17.ea.3.pma  | open    |            | 17.ea.3.pma-open    

where the "local only" business seems to confirm that the SDKMAN folks somehow pulled it from availability

[SethTisue]

what is 17.ea.3.pma, is it suitable for our use? my best guess is that "pma" is short for Project Panama, as in https://jdk.java.net/panama/ , and if I'm right, then no it is not suitable

[SethTisue]

there's no recent changes at https://github.com/sdkman/sdkman-db-migrations/commits/master/src/main/scala/io/sdkman/changelogs/java/OpenJdkMigrations.scala 🤷

SDKMAN needs to be updated to retrieve build 35? https://jdk.java.net/17/

[ashawley]

It's strange, because looking at old Travis builds from last week, it appears SDKMAN had no trouble pulling down build 33:

Using java version 17.ea.33-open in this shell.
openjdk version "17-ea" 2021-09-14
OpenJDK Runtime Environment (build 17-ea+33-2705)
OpenJDK 64-Bit Server VM (build 17-ea+33-2705, mixed mode, sharing)

[SethTisue]

I've reported it at https://github.com/sdkman/sdkman-candidates/issues/38

If this isn't resolved in the next few days I think we could just temporarily remove JDK 17 from the matrix until there's a fix or until JDK 17 final becomes available from the AdoptOpenJDK folks, whichever occurs first.

(I'm a bit annoyed we might need to do that in multiple repos, but oh well, things happen 🤷)

umbrella ticket on handling this org-wide (all scala/* repos): scala/scala-dev#787

[SethTisue]

I believe this is fixed now based on what I've seen in other repos
