In 1.1-M04, the following code fails when executed:

fun test() {
    val action = mock<() -> Unit>()
    MyJavaClass().doSomething(action)
}

public class MyJavaClass {

    void doSomething(Runnable r) {
        r.run();
    }
}

Now mock<() -> Unit>() uses Mockito to create a mock object. This mock object will by default return null when invoked: action.invoke() will return null.

Since M04, the following ISE is thrown:

java.lang.IllegalStateException: invoke(...) must not be null

	at test.SAMTestKt$sam$Runnable$3ede1671.run(SAMTest.kt)
	at test.MyJavaClass.doSomething(MyJavaClass.java:6)
	at test.SAMTest.test(SAMTest.kt:12)

Is this intended?
