One of the besting things about Java and having a strong IDE ecosystem. When I was working in Java 7 + Eclipse the ability to hotswap in changes to functions made debugging (even in production) a dream! Dropping a few new lines of conditional logging into a service was crucial for those 3am war room sessions. Now, working in Java 8 + Intellij hot swapping fails constantly because lambdas don't seem to compile is a stable fashion. Eclipse uses a more development friendly compiler ECJ so I wonder if it has this solved.
