JRuby 9000 is the newest major version of JRuby, representing years of
effort and large-scale reboots of several JRuby subsystems. It is expected

Major features of JRuby 9000:

    Ruby 2.x compatibility
    A new optimizing runtime based on a traditional compiler design
    New POSIX-friendly IO and Process
    Fully ported encoding/transcoding logic from MRI
