==== Summary ====
  * JVM support for dynamic languages, with the new invokedynamic bytecode under JSR-292, following the prototyping work currently done on the Multi Language Virtual Machine

  * These small language changes (grouped under a project named Coin):
    * Strings in switch
    * Automatic resource management in try-statement aka try-with-resources statement
    * Improved type inference for generic instance creation, aka the diamond operator <>

  * Timsort is used to sort collections and arrays of objects instead of merge sort
  * Library-level support for elliptic curve cryptography algorithms
  * An XRender pipeline for Java 2D, which improves handling of features specific to modern GPUs
  * New platform APIs for the graphics features originally implemented in version 6u10 as unsupported APIs
  * Enhanced library-level support for new network protocols, including SCTP and Sockets Direct Protocol
