Java. Migrating to 11 in real app

Conference

Java Language

It's (post) Java 11 time now. (Just in case your boss didn't notice ;-)
In this talk, I'd like to tell you how I managed to migrate two real Java server apps to Java 11 and show some demos.
Why was it done?
How to convince the business?
What and how was done?
What wasn't required?
Does anyone read licenses, manuals, and talks' descriptions?
Where did I fail in the first approach?
Was it worth it?
Some hints for you.

Java 12 & 13. What's new and noteworthy?

Deep Dive

Java Language

Hey, there were two major Java versions released since last Devoxx!
We don't have to wait 3 years or so for new features any more. Isn't that cool? ;-)
So... you'd like to check what has happened since Java 11?
Switch expressions? String blocks? New functions in String, Streams and other APIs? What are the Shenandoah and ZGC about? AppCDS to speed up spin-off?
If you find them interesting, let's dive deep together into new interesting stuff.
