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.
