The Red Hat build of OpenJDK

The Red Hat build of OpenJDK is based on the upstream OpenJDK 8u and 11u projects. Red Hat maintains these projects upstream and adds additional future features into our builds that are available for download here.


Commercial support for Eclipse Temurin

Red Hat also provides support for Eclipse Temurin, a distribution of OpenJDK built by the Eclipse Adoptium project. Eclipse Temurin is available to download from the Adoptium website (https://adoptium.net/).


​​​​​​​The Red Hat build of Cryostat

Cryostat is a container-native JVM application that provides a secure API for profiling and monitoring containers with JDK Flight Recorder (JFR).  It connects to the JVM targets to record and analyze data about threads, memory or heap consumption, garbage collection characteristics, and other performance metrics. Developers and DevOps can monitor, troubleshoot, and improve the performance of their applications by analyzing the data from Cryostat. The Red Hat build of Cryostat can be installed as an operator on the Red Hat OpenShift Container Platform.
