Mockito Test Method Transport.send inside completable future

So I'm struggling with writing a mockito test method for a method having this piece of code

            Future<?> future = executor.submit(() -> {
                try {
                    LOGGER.info("create Transport to send mail");
                    Transport.send(message);
                } catch (MessagingException e) {
                    throw new RuntimeException(e);
                }
            });

so Ive mocked ExecutorService and Future and tried doing this

        when(mockExecutor.submit(any(Runnable.class))).thenReturn(mockFuture);

but seeing this error

error: no suitable method found for thenReturn(Future<CAP#1>)
        when(mockExecutor.submit(any(Runnable.class))).thenReturn(mockFuture);
                                                      ^
    method OngoingStubbing.thenReturn(Future<CAP#2>) is not applicable
      (argument mismatch; Future<CAP#1> cannot be converted to Future<CAP#2>)
    method OngoingStubbing.thenReturn(Future<CAP#2>,Future<CAP#2>...) is not applicable
      (argument mismatch; Future<CAP#1> cannot be converted to Future<CAP#2>)
  where CAP#1,CAP#2 are fresh type-variables:
    CAP#1 extends Object from capture of ?
    CAP#2 extends Object from capture of ?
