Oracle Announces Java 8

Java SE 8 and Java ME 8 Together Make Major Steps Toward Long-Term Convergence

Oracle has announced the availability of JDK 8, a production-ready implementation of the Java SE 8 Platform Specification, which was recently approved through the Java Community Process (JCP). This release includes the largest upgrade to the Java programming model since the platform was introduced in 1996. JDK 8 was developed collaboratively in the OpenJDK Community.

Oracle has also announced Oracle Java SE Embedded 8, which leverages the new Java SE 8 features and is optimized for mid to high end embedded systems.

With a consistent Java 8 platform across embedded devices, desktops, data centers and the cloud, customers can deploy applications faster, process and analyze in-flight data and act on events as quickly as they occur.

Leveraging Java's cross-platform benefits, the Oracle Java Embedded implementations are designed to increase hardware flexibility and platform choice, allow easier application portability and help extend product lifecycles.

Java SE 8

  • The Java SE 8 release is the result of industry-wide development involving open review, weekly builds and extensive collaboration between Oracle engineers and members of the worldwide Java developer community via the OpenJDK Community and the JCP.
  • Java SE 8 enables enhanced developer productivity and significant application performance increases through reduced boilerplate code, improved collections and annotations, simpler parallel programming models and more efficient use of modern, multi-core processors.
  • The key features of JDK 8 are Project Lambda (JSR 335), the Nashorn JavaScript Engine, a new Date and Time API (JSR 310), a set of Compact Profiles and the removal of the "permanent generation" from the HotSpot Java Virtual Machine (JVM). A complete list of the new features and capabilities of JDK 8 is available here.
  • Oracle JDK 8 has already achieved world record performance for 4 socket systems on NEC Intel-based servers and for 2 socket systems on Oracle SPARC T5 servers, with a performance improvement of 12 to 41% compared to JDK 7 on the same Oracle configuration (NEC benchmark details, Oracle benchmark details).
