Thank you for your thoughtful and interesting comment.
I too like Java a lot and think it's a great technology.
I can see how a runtime for a compiler (such as the JVM) doesn't need to change much over time: if the compiler produces the right code in 2000, then the code is probably still right in 2020, it just could use more features of the ISA that were introduced since then.
On the other hand, the design of platform, library code and framework code is an ecosystem that is desperate to transform over time as better approaches to solving technical and business problems are found.
