The IcedTea project provides a harness to build the source code from OpenJDK using Free Software build tools, along with additional features such as a PulseAudio sound driver, the ability to build against system libraries and support for alternative virtual machines and architectures beyond those supported by OpenJDK.

This release updates our OpenJDK 7 support in the 2.4.x series with a number of security fixes and synchronises it with the upstream u45 b31 tag.

Existing users of the 2.3.x series are strongly advised to upgrade to the 2.4.x series. Although there will be a 2.3.x update, one security issue (CVE-2013-5838) is resolved by the JSR292 rewrite (S7023639) which is present in the 2.4.x series, but not 2.3.x. It may or may not be possible to backport this for the Zero port, but the safest solution is to use 2.4.x where possible.

If you find an issue with the release, please report it to our bug database under the appropriate component. Development discussion takes place on the distro-pkg-dev OpenJDK mailing list and patches are always welcome.

Full details of the release can be found below.
