[Live-demo] Which version of openjdk should be included on OSGeo-Live 6.0?

So here is my first impression with openjdk7:

Some packages are packaged as deb files and recommend openjdk6 since 
they are build against that default version in 12.04 (eg gvsig). Others 
require openjdk6 (eg atlastyler) and apt-get installs it in order to 
fulfill the dependencies.

So basically until all deb files involved here are built against 
openjdk7 in Launchpad, we will be getting both versions installed in the 

Basically this would require a lot of effort from packagers and I am not 
sure that the projects would like to have a version upstream that uses a 
Java version that is not the default of the OS. The golden rule in 
packaging is to try to offer users default versions of dependencies...
