The Java Mustang (JDK 1.6)

Proposed Specification

The proposed specification will define the feature set for the next major release of the Java 2 Standard Edition platform, code named "Mustang", which is targeted to ship in 2006. Mustang is one of a ongoing series of J2SE feature releases. The goal is to ship feature releases on a regular 18-24 month cycle, with each release including a combination of quality improvements and new features.

This JSR will not itself define any new features or enhancements; it will, rather, enumerate features and enhancements defined in other JSRs or through the JCP maintenance process.
It is expected that most of the effort in the Mustang release will be toward product quality (bug fixing) and stability, with relatively less work going into new APIs and other kinds of features.

The JSR expert group will define a specification consisting of a target feature set for Mustang. This target set will be further refined during the early-draft and public review periods and will become the target feature set for the release. The goal is for the Mustang release to include the full target set, but depending upon design and implementation schedules some items may be deferred to a later release if they are unable to make the Mustang schedule. The final specification will reflect the actual content of the Mustang release.


The major themes of the Mustang release are expected to be
* Compatibility and Stability
* Diagnosability, Monitoring, and Management
* Ease of Development
* Enterprise Desktop
* XML & Web Services
* Transparency
