> If there is an interface having the static method {{foo}} and a class {{Impl}} implementing
this interface also having a static method {{foo}}, then calling {{Impl.foo()}} calls the
method on the interface. For an easy self contained example have a look at https://github.com/wolfs/groovy-static-interface-method-test/blob/master/src/test/groovy/StaticInterfaceTest.groovy.
> This can yield class cast exceptions on Java 8 and from Java 9 build 125 onwards this
yields 
> {code}
> java.lang.IncompatibleClassChangeError: Method ... must be InterfaceMethodref constant
> {code}
> This verification has been introduced here: https://bugs.openjdk.java.net/browse/JDK-8145148.
