The developers of Fedora 21 are deciding what new features to implement and which packages to keep or to upgrade for the next version of the OS, and it seems that Java and OpenJDK are now up for review.
The new Java 8 was released recently by Oracle and it’s useless to point out that it comes with a wealth of new features and fixes. Any Linux distribution that is using Java will probably think about upgrading to the new version.
The Rad Hat developer also said that the current default Java runtime (Java 7, provided by OpenJDK 7, java-1.7.0-openjdk) used by Fedora 20 would be obsoleted and removed.
Keep in mind that this is just a proposal, but it’s very likely to happen.
