Is it worth it? Performance is not a reason for using Java 17. This is just source code, however, not a distributable build (think: your .zip file with the compiled java command for your specific operating system). It has undergone some changes since it was made default, including the ability to return unused committed memory to the OS (, A ZGC garbage collector has been introduced in Java 11 and has reached product state in Java 15 (, ).

It is still strongly typed, though, and only applies to variablesinside methods(thanks,dpash, for pointing that out again). As of Java 10, the container integration is enabled by default. It aims to keep the pause times low and independent of the heap size. Much of the improved performance comes from new features and optimizations in the JVM and in this post the focus will be on the improvements done in the area of garbage collection. Why is it, after more than 7 years, still the most commonly used version? A set of constructors can be also declared. the Machine Reassignment numbers (B1 and B10) fluctuate a lot between runs on the same JDK and GC.
