Liberica JDK and JRE distribution

Liberica JDK and JRE are distributed as .rpm, .deb and .tar.gz packages. Please select the one which is most appropriate for your purposes.

  • Use Liberica JDK if your application requires javac or other tools and services not present in a JRE, or you would like to use jlink to create a trimmed-down version of the Java Runtime for your particular needs.

Liberica 8 introduces all new features supported by OpenJDK 8 on Linux x64

By default, the Liberica uses Server VM. Server VM and Client VM can be enabled with -server and -client command line options, respectively. In case the deployment requires to minimize the footprint, it may be beneficial to use Minimal VM, which emphasises on a minimal footprint. It has C1 JIT compiler only, Serial GC and no serviceability features. In a JRE it can be enabled in runtime with -minimal command line option.

Linux x86 version of Liberica 8 also contains LibericaFX.
