Those previous benchmarks were run on a different codebase (OptaPlanner 7.44 instead of 8.10). Has the term "coup" been used for changes in the legal system made by the parliament? Web2. The Parallel Garbage Collector is 16.39% faster than the G1 Garbage Collector. Now, historically (pre-Java 8), there were actual source differences between OpenJDK builds and OracleJDK builds, where you could say that OracleJDK was 'better'. Additionally, there are quarterly bug fix updates. Other parts of the Java platform, for example the JIT compiler, also contribute to these improvements. Java versions before 9 simply had a different naming scheme. Make sure, you have the latest patch level 17.0.3 or later, due to CVE-2022-21449. In 2021, Microsoft published Microsoft Build of OpenJDK, yet another OpenJDK build. Apparantly, this is to avoid risks, especially lawsuits against Oracle. It obviously does not work the other way around, say your program relies on Java 13 features that are simply not available under a Java 8 JVM. and some libraries, Up until Java 8, you were pretty much using Oracles JDK builds and you did not have to care about licensing. On average, for OptaPlanner use cases, these benchmarks indicate that: Java 17 is 8.66% faster than Java 11 and 2.41% faster than Java 16 for G1GC (default). Declaring long strings does not often happen in Java programming, but when it does, it is tiresome and confusing. z o.o. It aims to reduce the pauses even further. So, when you had a machine with 16 GB of RAM, set your containers 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. Thanks, Stephen! Its arguably better to ignore the Machine Reassignment numbers. Applications of super-mathematics to non-super mathematics. Contrary to an enum, a record can be instantiated with the new keyword. See Baeldungs tutorial to get a general idea of how to use it and what one can get from it.
