Continue improving JDK 15 builds

[SethTisue]

#1225, now closed, was about getting the core of the build green on JDK 15

but there are still a lot of unnecessarily failing repos. there's no real rush, but we should gradually address them. also, as time passes, maintainers will probably address them themselves in their own repos.

I plan to focus on the 2.13.x build and worry about 2.12.x later.

failing projects at https://scala-ci.typesafe.com/job/scala-2.13.x-jdk15-integrate-community-build/1251/ (October 3):

Hi @SethTisue ,

Fs2 has updated to the latest sbt-osgi a few days ago: typelevel/fs2@8f899e6

I guess that should fix the issue?

[SethTisue]

@gvolpe thanks for letting me know. I'll get it in my next round of work on this.

UPDATE: done

[SethTisue]

I've been chipping away at this. current status (as of run 1293): SUCCEEDED: 215, BLOCKING DOWNSTREAM: mockito-scala (4), twitter-util (3), playframework (3), pureconfig (3), elastic4s (1), akka-persistence-cassandra (1), ip4s (1)

  val jdk15Failures = Set[String](
    "akka-persistence-cassandra", // needs newer sbt-osgi
    "avro4s",        // test failure: com.sksamuel.avro4s.github.GithubIssue387
    "elastic4s",     // Unrecognized VM option 'CMSClassUnloadingEnabled'
    "ip4s",          // needs newer sbt-osgi
    "mockito-scala", // reflection-related test failures
    "playframework", // Failed tests: play.mvc.HttpFormsTest
    "pureconfig",    // needs newer sbt-osgi
    "twitter-util",  // Unrecognized VM option 'AggressiveOpts'
    "zinc",          // sbt.inc.Doc$JavadocGenerationFailed
  )

I'm feeling like this is now good enough as far as my own efforts are concerned — volunteer contributions remain welcome

[SethTisue]

oh, for the record, on 2.12.x the status (as of run 1170) is: SUCCEEDED: 157 and BLOCKING DOWNSTREAM: akka (25), fs2 (9), twitter-util (4), sbt-util (3), scala-async (2), scala-logging (2)

and I think that's good enough. that's enough green to give good assurance that Scala and sbt are working, and addressing the remaining failures would be too annoying since so much of the 2.12.x build is now frozen
