Plan upgrade to version 17 within the next months. When improving the collectors, one big part is to make sure that the tradeoffs are done as efficiently as possible. Simply switch your JDK installation and you get a free performance boost. Even more can be achieved with the new yield keyword that allows returning a value from inside a code block. Now, the version number looks like this: Coming from other programming languages with major breakages between releases, like say Python 2 to 3, you might be wondering if the same applies to Java. 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. CPU is completely saturated. The other numbers dont suffer from this unreliability. What does it do? Java 17 has below proposed features coming out as part of the JDK 17:410: Remove the Experimental AOT and JIT Compiler398: Deprecate the Applet API for Removal391: macOS/AArch64 PortJEP 382: New macOS Rendering PipelineJEP 356: Enhanced Pseudo-Random Number Generators Now, the programmer knows exactly what will happen when the object is not found. cloud optimization. Deciding which garbage collector to use is not always obvious. and some libraries, Up until Java 8, you were pretty much using Oracles JDK builds and you did not have to care about licensing. It aims to reduce the pauses even further. ZGC does such a good job keeping the pauses short that we start to see other things affecting the latency score. Its certainly a solid reason to consider moving to the new version of Java. But the only real change you as a developer will likely see is the introduction of the varkeyword, also called local-variable type inference. In terms of language, its kind of similar to an enum.
