Subject Re: Can we drop Java 1.5 support in Cayenne 3.2?
Date Mon, 16 Jul 2012 02:03:51 GMT
Yes, dropping 1.5. Which is really all about dropping support for any 32bit Mac. Windows and
Unix/Linux machines can run 1.6 on old 32bit hardware. But OSX will not.

I think we should be careful to frame this conversation around years rather than generations.
Apple are moving to a 'release often' approach which means that a generation may only be 18
months. I notice that many of my customers never bothered going from 10.6 to 10.7 since there
were very few new features they cared about. For the Cayenne project that means we may need
to support older Java releases for longer.

Sorry I introduced the red herring of Java 7. I've recently been trying to get my head around
what is happening there on OSX, and found few clear answers.
