RFR: JDK-8209022: Missing checkcast when casting to type parameter bounded by intersection type

[Maurizio Cimadamore]

Looks good.

The test could be simplified either by using TestNG (which supports 
assertions for exceptions), or by defining an helper function which 
takes a Runnable. Then you can pass it two method references ::f and ::g 
and the helper function could call them and check for exceptions.
