Yesterday I was invited to an expert panel accompanying the JDK 11 Release. Thanks to Oracle and the DPunkt-Verlag, that organized the event. We had a lot of fun discussing new features, the new licensing model, but also issues that did not go so well in this release. The video is in German.

If you just want to try things out, I recommend using the OpenJDK, because you can use it for anything without having to worry when to buy a commercial license.
