The IcedTea project provides a harness to build the source code from OpenJDK6 using Free Software build tools, along with additional features such as a PulseAudio sound driver and support for alternative virtual machines.

A new set of security releases is now available:

  • IcedTea6 1.8.10
  • IcedTea6 1.9.10
  • IcedTea6 1.10.4

Full details of each release can be found below.
