The JEE stack is a monolith with many deeply intertwined components. The alternative is having a stack composed of small focused libraries that can be composed to fit the needs of the particular application. I'm not talking about understanding the finer points of the internals such as the implementation of the TLS cypher. I'm talking about the complexity of how different moving pieces fit together in the stack. This isn't FUD, it's the reality and it causes security breaches all the time in the real world.
