Scala.js 1.0 fails to read transitive jsDependency

See original GitHub issue

I’ve got a PR for scalajs-react to cross-compile to SJS 1.0. The SJS 0.6.32 tests pass fine but for SJS 1.0 I’m getting this error:

I don’t directly specify prop-types in my build, it’s a transitive dependency of one of the react jsDependencies.

In 0.6.x we used ZipInputStream to open jar files. In 1.x we use java.nio.file APIs. From what you say it seems walkFileTree had a bug in JDK 8 that was fixed in 11.

Regardless, I think this jar is borderline. One shouldn’t put nameless directories in a jar.

Did some more digging. Of SJS {0.6, 1.0} x JDK {8, 11} this only occurs with SJS 1.0 & JDK 8. Why does it occur with SJS 0.6 & JDK 8?
