Support Java 21 on Scala.js #398

Open ekrich opened 1 month ago

ekrich commented 1 month ago

Scala.js does not work for Scala 3.3.x. Classes extending java.util.SequencedCollection cause problems. Note that Scala Native has the class added although it is just a stub at this time.

Reproduce:

  1. Run Java 21
  2. sbt
  3. ++3.3.4
  4. Run sconfigJS/test or one of the testOnly seen below.

Example error:

[info] Fast optimizing /Users/eric/workspace/sconfig/sconfig/js/target/scala-3.3.3/sconfig-test-fastopt
[error] Referring to non-existent class java.util.SequencedCollection
[error]   called from org.ekrich.config.impl.SimpleConfigList

Now running the newest code I get the same as below.

sbt:sconfig-root> sconfigJS/testOnly ConfigValueSharedTest

Another place it seems to occur.
