Java. Migrating to 11 in real app

Tags:

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.
