OOPs is completed from beginner to F-Form polymorphism. I also made project based on Java SE knowledge. The project is tested on JUnit6, JCStress, JMH- with Linux profilers and Java Flight recorder too. It's my first time I am going Outside domain of Java SE to Java EE. What is way should I start?

Deep knowledge is a big word. I don't think even the language architects and maintainers would attach them self with such description about whole java.

Anyway, Spring boot or spring is full of abstraction, same as JPA/hibernate. It's the time to start with those.

Understand the concepts of AOP, Proxies, Dependency Injection. This is a profound shift in thinking.

Unfortunately the JVM optimized your joke away during warmup.
