Has there been any further investigation to see whether or not Kepler and
Ptolemy compile and run properly under Java 1.7?Thanks,

I think your logic is sound. We need to stick with 1.6 until 1.7 is
mainstream on the platforms we support, including Macs. Its worthwhile to
be sure Kepler and Ptolemy II both compile and run properly under 1.7 now,
so that if people want to use it, they can. But lets not require it at
this point.
