1. Remove final keyword in front of method name in final class.
  2. ReadSubscription class is declared as final class. So I think final keyword is not needed with methods in ReadSubscription class.

@divcon I am afraid I am not keen to process this PR. It mixes style change (such as removing final keywords) with Java 17 API usage. k and v are not really variable names we'd use. In short, it'd take us more time to polish this than doing this ourselves. Thanks anyway.
