If you want to see a full list of changes to JDK, you should know that they are tracked as JEPs (JDK Enhancement Proposals). These distributions differ in licenses, commercial support, supported platforms, and update frequency. Java 9 got theJigsaw Module System, which somewhat resembles the good oldOSGI specification. The benchmark has a few different modes and it produces both a throughput metric and a latency metric. There were several examples and none were problematic. Theres two main feature sets Id like to mention here: Language Actually, this is more of a JVM change than a Java one as the bytecode analysis to build the detailed message is performed at runtime JVM but it does appeal to programmers a lot.
