Oracle announced today in a blog post that they will be moving to a plugin-free Java by deprecating the once common Java web plug-in in Java 9. The plug-in support will then be dropped in a later Oracle JDK/JRE release.
Oracle is doing this due to the browsers upstream working to eliminate NPAPI plug-in support. Oracle encourages web developers to either move to their plugin-free Java Web Start tech, create a standalone native install bundle for Windows/OSX/Linux of your Java code, or come up with a standards alternative.
Other expected Java 9 changes include a new jshell command line tool, full HTTP 2.0 support, a possible new garbage collector, Project Jigsaw for making Java more modular, and more. Oracle is expected to officially release Java 9 in 2017.
