Java 8, which was released in March 2014, is currently used by 69% of programmers in their main application. Why is it, after more than 7 years, still the most commonly used version? There are many reasons for that. Java 8 provided lots of language features that made Java Developers want to switch from previous versions. Lambdas, streams, functiona...
This article covers only the changes that I deemed important enough or interesting enough to mention. They are not everything that was changed, improved, optimized in all the years of Java evolution. If you want to see a full list of changes to JDK, you should know that they are tracked as JEPs (JDK Enhancement Proposals). The list can be found in ...
Project Jigsaw
JDK 9’s Project Jigsawsignificantly altered the internals of JVM. It changed both JLSand JVMS, added several JEPs (list available in the Project Jigsaw link above), and, most importantly, introduced some breaking changes, alterations that were incompatible with previous Java versions. Java 9 moduleswere introduced, as an additional, highest level of jar and class organization. There’s lots of introductory content on this topic, like this one on Baeldungor these slides from Yuichi Sakuraba. Th...
Garbage Collectors
As of Java 9, the G1 is the default garbage collector. It reduces the pause times in comparison with the Parallel GC, though it may have lower throughput overall. It has undergone some changes since it was made default, including the ability to return unused committed memory to the OS (JEP 346). A ZGC garbage collector has been introduced in Java 11 and has reached product state in Java 15 (JEP 377). It aims to reduce the pauses even further. As of Java 13, it’s also capable of returning unus...
Container awareness
In case you didn’t know, there was a time that Java was unaware that it was running in a container. It didn’t take into account the memory restrictions of a container and read available system memory instead. So, when you had a machine with 16 GB of RAM, set your container’s max memory to 1 GB, and had a Java application running on it, then often the application would fail as it would try to allocate more memory than was available on the container. A nice article from Carlos Sanchezexplains t...
To keep it short: yes, you should. If you have a large, high-load enterprise application and still use Java 8, you will definitely see better performance, faster startup time, lower memory footprint after migrating. Programmers working on that application should also be happier, as there are many improvements to the language itself. The cost of doi...
Java 17 LTS is going to be supported for years to come. On the other hand, Java 8’s support has ended. It’s certainly a solid reason to consider moving to the new version of Java. In this article, I covered the most important language and JVM changes between versions 8 and 17 (including some information about the Java 8 to Java 9+ migration process...

- Restore Always-Strict Floating-Point Semantics. This JEP is targeted toward scientific calculations that involve floating-point numbers. To guarantee the same calculation result on all platforms, we have been using the keyword strictfp.
- Pattern Matching for Switch (Preview) This change adds pattern matching for switch statements and expressions. Since this is a preview feature, we need to use ‘–enable-preview‘ option to enable it.
- Sealed Classes. In Java, by default, there has been no restriction on a class which public interfaces it can implement. From Java 15, we can declare a class or interface sealed class or sealed interface using the modifier ‘sealed‘.
- Enhanced Pseudo-Random Number Generators. 2.4.1. RandomGenerator. This JEP introduced a new interface called RandomGenerator which aims to make future pseudorandom number generator (PRNG) algorithms easier to implement or use.

Jan 19, 2023 · Each new version of the OpenJDK brings new and experimental features, including speed and memory improvements. So it would make sense to upgrade all your runtime environments each time a new version becomes available. But that would involve testing and upgrading all your servers and/or applications every six months.
