[kepler-dev] moving Kepler to 1.6

[Derik Barseghian]

Hi,

Does anyone object to Kepler requiring Java 1.6?

I haven't moved Kepler trunk's Ptolemy version forward yet because  
doing so would mean we require 1.6, and I want to check with everyone  
first.
We are falling out of date with Ptolemy, and as we know this may make  
rejoining Ptolemy head problematic.

Some things to note:

* this will cause problems for non-64bit <10.6 macs, unless something  
like SoyLatte is installed (so as to have a 1.6 java -- I have this  
problem and would want to update to 10.6 (which has 1.6 for 32bit)  
before I did the update).

* At the end of this thread, Jianwu mentions a problem compiling  
Kepler under 1.6 on a x86_64 GNU/Linux machine. Is this still a problem?
https://kepler-project.org/developers/kepler-development-forum/build-and-release-team/496635000

* In that thread Matt mentions the NMI nightly builds are running on  
1.5. Is this still the case and should it block us from moving to 1.6?

Thanks,
Derik
