[kepler-dev] Java 1.7

To my knowledge, Ptolemy II and Kepler compile and run properly under
Java 1.7.
The Ptolemy II nightly build runs under Java 1.7.0_03 under Red Hat.
There are no known reasons that Ptolemy II or Kepler will compile and
run under Java 1.7.
The issue below is that the core of Ptolemy II and Kepler probably
should not require Java 1.7 until such time as Mac OS X ships with Java
1.7.
Mac OS X 10.7.5 ships with Java 1.6.0_37.
There have been some issues with Mac OS X 10.8 and Java 1.6.0_37, see
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5725
It looks like Oracle's Java 1.7 for Mac is out of prerelease. However,
if Ptolemy II and/or Kepler use features that require Java 1.7, then
installing Ptolemy and/or Kepler on the Mac will also require installing
Java 1.7 which seems like a rather high barrier of entry that is likely
to cause some users not to install Ptolemy and/or Kepler.
So, for the near term, Ptolemy II will still compile with Java 1.6, but
Java 1.7 will work.
