toJava call on future converter causes java.lang.NoClassDefFoundError: scala/concurrent/java8/FuturesConvertersImpl$CF,

[jasongoodwin]

Hey,

on v0.2.0 published to maven,
I've produced a barebones sbt project with only the scala-java8-compat library.
You can recreate by running sbt test on this project:
https://github.com/jasongoodwin/future-converters-problem

There is a unit test that fails:

@Test
public void itShouldNotFail() {
    Future future = promise().future();
    final CompletionStage cs = toJava(future);
}

It causes this exception

Thanks for the report. Looks like the OSGi packaging in our build stripped those classes out of the final JAR. 😢

I'll cut a new release as soon as the fix is reviewed and merged.

That's for publishing this so fast.
