Oracle is announcing its plans for advancing the Java Platform, Standard
Edition (Java SE) and optimizing it for new application models and hardware,
including extended support for scripting languages, increased developer
productivity and lower operational costs.
The announced roadmap for the OpenJDK accelerates the availability of Java
SE with two releases, one in 2011 and one in 2012. These OpenJDK
releases will continue to serve as the basis for the Oracle Java Development
Kit (JDK) 7 and JDK 8.
The decisions regarding the features to be included in the JDK 7 and JDK 8
releases were made with active participation of the Java community.
The OpenJDK project continues to thrive with contributions from Oracle, as
well as other companies, researchers and individuals. The OpenJDK
licensing model remains the same.
Oracle is currently working to merge the Oracle Java HotSpot Java Virtual
Machine (JVM) and the Oracle JRockit JVM into a converged offering that
leverages the best features of each of these market-leading implementations.
Oracle plans to contribute the results of the combined Oracle Java HotSpot
and Oracle JRockit JVMs to the OpenJDK project.
The Oracle JDK and Java Runtime Environment (JRE) will continue to be
available as free downloads, with no changes to the existing licensing
models.
Premium offerings such as JRockit Mission Control, JRockit Real Time, Java
for Business and Enterprise Support will continue to be made available for an
additional charge.
Proposed Features of JDK 7 and JDK 8

Proposed JDK 7 Features
o InvokeDynamic byte code and supporting features for dynamic
languages
o Fork/Join Framework and related concurrency and collections API
enhancements for improved multi-threaded Java code
o Small Language Enhancements (most of “Project Coin”) for higher
developer productivity and cleaner, more concise Java code
o Session Description Protocol (SDP) and Stream Control Transport
Protocol (SCTP) support
o New I/O APIs – A flexible filesystem API, and asynchronous I/O
o Support for updated standards - Unicode, localization, security,
cryptography, XML and JDBC
o JVM performance improvements

Proposed JDK 8 Features
o Lambda expressions (”closures”) for higher developer productivity and
better leveraging of multi-core CPUs
o Small language enhancements (Remaining parts of “Project Coin”)
o A Java-native module system (“Project Jigsaw”) to simplify the
construction, packaging, and deployment of applications
o JVM start-up time and ergonomics improvements
The lists above are examples and not exhaustive, see
