Java EE 7 JSRs Filed and Apple Makes Code Contribution to OpenJDK

Java EE 7 JSRs Filed

Work on Java EE 7 has taken another step forward, with the filing of two new JRSs. These are JSR 338: Java Persistence 2.1 and JSR 339: JAX-RS 2.0: The Java API for RESTful Web Services. The JPA 2.1 JSR covers support for using custom types and transformation methods in object/relational mapping, and support for multitenancy. Additional event listeners and callback methods are also discussed. JAX-RS 2.0 concerns the Client API, and integration with Bean Validation for parameter validation. Voting for both JSRs is now open, and the ballot closes on Jan 24th, 2011.

Apple Make First Public Code Contribution to OpenJDK

Apple have made their first public code contribution to the OpenJDK project for Mac OS X. This contribution modifies the build process to create universal binary, and produces a .jdk bundle which is recognisable by Java Preferences and the JVM detection logic in Mac OS X.

"It has been a long road getting to this point collaborating behind the scenes with Sun and now Oracle, but as of today we are on the road to fully open development of the Mac OS X port. We look forward to providing more code from our collaboration soon, and working with you all," said Apple's Mike Swingler.

Scala Team To Double?

The Scala research group at EPFL have announced they have been awarded a five year European Research grant of more than 2.3 million Euros, to address the "Popular Parallel Programming" challenge. This will allow the Scala team to nearly double in size. The Scala team will provide mechanisms that aim to allow a simpler programming model for common problems that benefit from parallel processing. Scala 2.9 will use multiple cores to increased performance using parallel collections.

"With this significant new research investment Scala's long term support is further assured and developers can look forward to continued state-of-the-art performance improvements," reads the announcement.
