Modularity, integration and serviceability are some of the main goals for future releases of Java SE, Java EE, and Java for Embedded Platforms. Mark Reinhold, Roberto Chinnici and Greg Bollella spoke at JavaOne 2010 Conference General Technical Session on Tuesday on new Java technologies and features in JSE, JEE, and Java Embedded Systems.
Mark spoke about the new projects and features which include Project Coin, Project Lambda, The DaVinci Machine Project (JSR 292), and Project Jigsaw. These features will be offered in the upcoming Java SE 7 (target release in mid 2011) and Java SE 8 (mid 2012) versions. He also talked about other features like adding bulk data operation logic to Collections API using filter and map operators in new classes like Predicate and Extractor, to simplify the code using Lambda expressions. Another new language feature is to add default methods to interfaces like Collection.
Modularity features will support a new packaging format called jmod for better compression. The developers will also be able to generate other formats like rpm, deb (debian) or Ubuntu packages. In the serviceability space, Java Virtual Machine (JVM) convergence effort will include merging Oracle's JRockit and Sun's hotspot virtual machines. This integration will be based on the hotspot code base and JRockit code will be ported to hotspot code. The new solution will take advantage of JRockit's Mission Control and Flight Recorder features.
Roberto Chinnici gave an overview of new features added in Java EE 6 release which include Web Profile, EJB 3.1 Lite, Pluggability and Extensibility, and Dependency Injection. He also spoke about the role of Java EE in Cloud Computing space, with the support for comprehensive security model, standard APIs for NRDBMS (NoSQL databases), caching and common management interfaces.
Greg Bollella, Chief Architect at Oracle's Embedded Java team, talked about the Java ME projects Java ME.Next and JavaME Plus Web and the new Light Weight User Interface Toolkit (LWUIT) framework.
