This is a reproducer of a bug in Kotlin as reported in youtrack.
class FunctionCheckTest {
@Test
fun passIsCheck() {
if ({ str: String -> } is Function<*>) {
} else {
fail("Function not recognized in `is Function<*>`")
}
}
}To run:
./gradlew jvmTest <---- passes
./gradlew jsTest <---- fails
Originally thought this was a bug with typealias, however the bug exists with functions.
Behavior is not consistent between platforms. JVM passes. JS & Native fail. Only JS tests run on this project due to difficulty setting up tests. This has been observed to fail in the native environment.
