Well, I guess that there isn't such thing like "fight back", I fight back enemys and I don't see this frameworks as it. Every framework has it uses, for a start-up I think this technologies could fit (Spring Boot), we can learn from their advacements and even incoporate it if it proves to be something that worth it (no shame on that).
Docker it's something complementary I can still use it with my Java EE apps, doesn't see why not, It save some time to a new developer set-up a environment and it's more easy to control this environmen across all devs.
And Jigsaw is here to stay, It's part of Java now, and in my point of view, a necessary one, I will use only the parts that suits my needs, I don't see how it could be a bad thing.
But you have a point when you said " A lot of people seem to not understand JavaEE", here is where we can do something, we can teach and show the learn path for this awsome tool that is Java EE. I really didn't have someone to teach me so my path to learn it was a little bit rough, what has helped me along the way was the Java EE Tutorial and it's examples, I would like to say a big thank you for everyone involved in the Java EE Tutorial, I guess I wouldn't love Java EE like I do now and I don't know if I would have a job if weren't for you.
That's it, we have a awsome and powerful tool, let's spread the good news.
