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

Mon Jun 4 05:23:35 PDT 2012

Hi,

ok, the next step for this will be to evaluate alpha3 for the next few days
and see what broke.

What should be our policy in case of a project still dependent on openjdk6
close to release date? Shall we exclude it from the disk for version 6.0?

This means that only openjdk7 will be available and that all applications
must use it, without special bundled jre's.

As Alex explained the packaging issue is easy in debian conf files. This is
because openjdk is available from upstream, so no need for third party
repositories.

I will test the last build and report back issues.

Cheers,
Angelos
