[Live-demo] Java apps: better get working on your OpenJDK port ...

I'm forwarding this email onto the OSGeo-Discuss list, as Hamish has 
identified the high impact implications of Sun/Oracle licencing, which 
seems to imply that most OSGeo java based projects will need to start 
supporting OpenJDK if they wish to support most users on linux based 
operating systems.


As outlined by Hamish below, the Sun/Oracle Java cannot legally be 
installed using ubuntu installers - people will need to download from 
the Oracle website instead.
We possibly could use Sun Java with the next, March 2012 based OSGeo 5.5 
release (as we are basing upon the old Xubuntu 11.04), but we would 
probably not be able to legally include any java based security updates.

For OSGeo-Live 6, for FOSS4G 2012 in Sept, we will likely only have the 
option of using OpenJDK and not Sun-Java.

I'd like to hear advice from each Java based projects as to the 
feasibility of migrating to OpenJDK, and what you recommend we do on the 
OSGeo-Live project.

Please respond on the live-demo at lists.osgeo.org list.
