Which version of JDK should I use?
Here&#x27;s my recommendation (I work on OpenJDK at Oracle):<p>If you&#x27;re using the current JDK version (recommended for regularly maintained applications), it doesn&#x27;t matter which distribution you choose, as they&#x27;re all pretty much identical. If you&#x27;re using an old version (LTS, intended for legacy applications, which might benefit from it), pick a vendor you trust for OpenJDK support, as the builds are <i>not</i> the same, and neither is the support. After Oracle, which contributes about 90% of the work on OpenJDK, the companies distributing builds that contribute to the project and have experience with it are (in rough order of experience and&#x2F;or contribution): Red Hat, SAP, Azul, Bellsoft, and, more recently, Amazon, and Microsoft.<p>There are, however, a couple of standouts: Alibaba&#x27;s Dragonwell, which, last I looked, did not meet the Java specification, and Eclipse Adoptium, built by IBM, which is the only distribution built by a team that isn&#x27;t involved with the OpenJDK project, isn&#x27;t very familiar with it, and isn&#x27;t a member of the OpenJDK Vulnerability team, and so get security patches only after the other vendors have delivered their builds.
