Oracle is currently hard at work on JDK 9, which will include Project Jigsaw, an effort to modularize Java. JDK 9 is also the first version of the language for some time to take a machete to some of the least-used Java internals. This work began in JDK 7 (MIDI support was removed from Java) and continued in JDK 8, but JDK 9 should see the most deprecation of any of the open-source Java efforts.

JDK 9, available as an early-access release, will be the first to eliminate browser-based Java applets in favor of Java Web Start-based applications.
Oracle blamed this deprecation on modern browsers and their slow move away from plug-ins. This move is evidenced by the diminishing popularity of technologies like Flash, JavaFX and Silverlight.
