We are pleased to announce the release of IcedTea 2.5.2, “Back in the Groovy”!

The IcedTea project provides a harness to build the source code from OpenJDK using Free Software build tools, along with additional features such as 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 with a number of regression fixes found in the previous 2.5.1 release. Mostly notably, it includes a backport of a regression fix. With the previous release, a number of Java tools and applications, including Groovy, were broken. This release should resolve these issues.

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.
