I'm struggling with this exercise. The compiler seems to get crazy after I entered the asked code. "Bummer! java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.RuntimeException: No toolkit found (Look around WaitForAsyncUtils.java line 150)"

Treehouse TeacherLooking into this...will keep you updated. Problem with a missing library on the server that I am using to test.
Sorry for the frustration!

Changing the JDK worked on my local machine, I hope the solution is as simple as that :P

3,633 PointsThanks Javi, but it works without problems on my local machine. On the online compiler it keeps getting this error, I observed that it does that only when I use Lambda
