Hello community, I want to open a discussion about build bookkeeper on java11 ## Motivation Currently, bookkeeper keeps the compatible with java8. Java11, a lts version of jdk, provides new features and performance optimization. And Java11 was released in 2018 and is now mature. I think it's time to migrate to java11.
## Breaking Changes java8 is not supported ## Release plan Including this in bookkeeper 4.16.0 original issue https://github.com/apache/bookkeeper/issues/3313
