The idea page for this year's GSoC can be found here.
We will not apply as a mentoring organization for Google Summer of Code in 2014.
Do not let that stop you from participating in Google Summer of Code, though. There will be a lot of very interesting projects to choose from.
In particular, it is likely that the GNU Classpath project will take part in GSoC 2014 under the umbrella of the GNU foundation. OpenJDK or IcedTea might also take part in GSoC 2014.
