Subject Re: Java 6 for 3.1?
Date Sun, 30 Jan 2011 10:05:02 GMT
I guess we bag the upgrade for now then. At least the next time we discuss it, we will already
know that there are no objections, except for this specific edge case of PPC and early 32-bit
Intel Macs (I actually have one from the later category, used by my company QA). 

(Wonder if there is a 32-bit version of OpenJDK 7?)

reason: generics. This time around, there is nothing really to be gained and we immediately
remove any PPC Macs from the userbase.

a 'copy' of Java 5) for some new tablet application, they may well be targeting Java 5. Personally
I still have a couple of PPC machines in the office and they are only 4 years old. Many of
my customers have refresh cycles much longer than 4 years, especially in the education industry.
