Good! I am really looking forward to jshell, yet I appreciate that the Java team at Oracle is taking it's time to get this right. With their very strict backwards compatibility requirements (still compatible with Java 1.0 AFAIK), everything they release to the public, they must maintain forever.
Side note: Can somebody please write a concise tutorial about how to use the new features (like this awesome Java 8 tutorial: https://github.com/winterbe/java8-tutorial )? If you do, contact me. I would love to help out, but I don't have much time at the moment...
