Have a look at how JavaDelegates and ExecutionListeners are implemented in the kotlin/java example.

Manual code delegation in java implementation is ugly ... but to get kotlin's interface defaults and delegates/implemented by working with java we would need the @JvmDefault flag which is experimental in kotlin 1.3 and requires a compiler arg ...

so this might be moved to kotlin when 1.4 is out ...

Please provide enough tests to climb at least above 60% of coverage... and please provide comprehensive documentation here...

Closing for now.
