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 in the 2.5.x series with the October 2014 security fixes.

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.

Note that alternate virtual machines (e.g. CACAO, JamVM) will be broken by this release, until such a time as they introduce support for JVM_FindClassFromCaller, a new virtual machine interface function added by S8015256

Full details of the release can be found below.

The tarballs can be downloaded from:

We provide both gzip and xz tarballs, so that those who are able to make use of the smaller tarball produced by xz may do so.

The tarballs are accompanied by digital signatures available at:

These are produced using my public key. See details below.
