![]() Below is a comparison of latency (shortening the app's work interruptions) between J8 and J17. Java 17's GC is faster and more efficient than its predecessors on every level. ![]() Thanks to it, your system (application, program, website) is constantly cleaned of unnecessary data, so it doesn't fill up and works quickly and efficiently. One fundamental performance change not available for older Java versions is the new, improved G1 and ZGC Garbage Collector.Ī Garbage Collector is a built-in program that automatically and continuously manages your system's memory. In addition, with Java 17, companies get access to features that improve system performance and thus the work speed of all employees. Please take a look at this list to have a glimpse of the repair scale. And Oracle will no longer patch those.Ĭompanies that don't update Java will be more vulnerable to data leakage and other security weaknesses. The number of security and performance issues that are fixed regularly is vast. Each version has security issues the older the version, the more holes it has. The lack of support by Oracle also means the lack of access to security patches. As a result, companies working on old Java won't have access to technical support. Their systems will grow slower than competing ones running on Java 17 and newer. In other words, Oracle stops investing in Java 8 and won't develop it as it will develop new versions. As they officially pointed out, "their effort put into maintaining it will likely be significantly smaller than it is right now." Oracle no longer includes Java 8 with PremierSupport. Some Java releases come out in the form of LTS (long-term support), which in the case of Java 8, ended in March 2022. If you want a more detailed explanation, contact me directly. Popular, old (J8), and the latest LTS-covered versions (J17) for an easier understanding of the trends. ![]() Still, I will simplify the examples to the most Some features are available in earlier Java versions. Most cases, the following changes compare Java 8 and 17, but not all of them. Today I will break down all the changes, benefits, and new features of the latest Java versions that I believe make a big difference in how companies and their software work. If something works, then there’s no need to change it.Īnd while this logic definitely does apply to many business cases, the recent changes in the Java world leave no doubt: if you don't update the system, you will fall behind both business and technology-wise. Often it's because entrepreneurs assume that the better is the enemy of the good. We've been working with DACH companies since 2014, and we can see that many of them are reluctant to major Java updates. ![]()
