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).=20

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