This beat is now ready to have Fedora 25 content added by the beat writer
Java
More efficiently dependency management for Java packages
The way that Java dependencies are handled has changed in Fedora 21. Packages that do not interact with the X server or audio subsystem, now depend on a new OpenJDK headless subpackage. This means installation size reduction on servers, a change that aims for efficiency.
Java packaging guidelines now require to convert most Java packages to have "Requires: java-headless" when appropriate. Changes can be found at Fedora wiki:
https://fedoraproject.org/wiki/Packaging:Java#BuildRequires_and_Requires
Javadocs subpackages no longer mandatory
Another change to Java packaging guidelines regards to Javadocs subpackages, which are now optional in Fedora packages.
Update to OpenJDK 8
OpenJDK8 is now the default Java Runtime in Fedora, replacing OpenJDK7. A full list of the features added in OpenJDK7 is available upstream at http://openjdk.java.net/projects/jdk8/features/.
User customizations made to java-1.7.0-openjdk (specifically, to files under /usr/lib/jvm/java-1.7.0*/*) will not be carried across to java-1.8.0-openjdk.
