Detailed Description

Oracle made available the first proprietary JDK7 release on 2011-07-28. Java 7 brings several significant changes and Fedora should supply a build of OpenJDK7 along-side the existing OpenJDK6 packages initially, and then only ship 7 once it has proven stable.

Benefit to Fedora

Fedora will remain up-to-date with regards to the Java platform. Developers using Java on Fedora will have access to new features.

Scope

This would require building and packaging the new JRE and JDK, and updating any packages that may be incompatible with Java 7 based on this list:

How To Test

Install java-1.7.0-openjdk Run (as root) 'alternatives --config java' and select the 1.7 version Run 'java -version' to ensure that it is correct


User Experience

Changes will be present but not prominent or massive for most users. Users who install Java will see a new version of the JRE. Developers who target for the Java platform will have a new version of the JDK installed.

Dependencies

Packages involved in the JRE and JDK will need to be changed depending on if there are compatibility issues:

Contingency Plan

Java 6 will be kept in the repository until Java 7 is proven stable.
