You've spot a bug:
(int) methodHandle.invokeExact(); // error: not a statement
should compile.

The compiler should consider it as a statement, like it does
for invokedynamic.

If you use a dummy variable, it works:

     int foo;
     System.out.println("\n\nATTEMPT 1");
     foo = (int)InvokeDynamic.anything();

     System.out.println("\n\nATTEMPT 2");
     foo = (int)methodHandle.invokeExact(); // warning: unchecked 
generic array creation

     System.out.println("\n\nATTEMPT 3");
      foo = (int) methodHandle.invokeExact(); // error: not a statement
