Java 6 for 3.1?
Since Java 5 has been EOL'd for some time, and Java 7 seems to be close to GA, (and there's no more Java 5 on OS X, so I've no idea whether Cayenne is really java 5 compatible :-)), how about we make Java 6 a minimal JVM requirement for Cayenne 3.1? Keeping things tight and all that.
Comments?

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?)

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.

There's nothing new in Java 6. JDBC 4 I guess is one area where we won't need a bunch of hacks that we are using now (org.objectstyle:jdbc-compat). This and Maven hacks to maintain 1.5 and 1.6 builds in parallel can go away.

+1. Every where I do work has switched over to 6.

+1. Even I am using Java 6 now, and I'm usually a laggard.
