== Java
Release 43 makes `java-25-openjdk` available in Fedora, the latest LTS version released Sept. 2025.
The `java-21-openjdk` is still available in F43 and will continue to be in F44. It will be removed in F45.
In Fedora 43 both openjdk versions provide "java" equally. There is no "system" or "default" JDK anymore. Users can (and should) choose which version to use, and can mix and match Java versions for development and runtime. Several instances of a software, e.g. Tomcat, can execute with different Java versions. Conventionally, the most recent version will likely become the systemwide used default one, but there is no guarantee. Use `alternatives --config java` to select the version to be used systemwide by default.
Upgrading from release 42 with installed java-21-openjdk, just updates Java 21 to release 43. The upgrade does not automatically update to Java 25. The administrator must install these separately.
For more information about Java 25, see the link:++https://jdk.java.net/25/++[JDK 25 Features and Release notes].
