The only reason I know of to stick with Java 1.6 is that the version of
Java that is supported by Apple for Mac OS X 10.7.
This is the version of MacOS X that runs on three year old Macs, such as
the one I'm using right now.
Apple is still supplying patches for Java 1.6, see
http://support.apple.com/kb/ht5982, updated last October.
However, Java 7 is available for the Mac.
Requiring Java 7 is probably ok, but there could be some support costs
in that Mac users will need to install Java before installing Kepler.
One additional complication is that the disk layout of Apple's 1.6 Java
and Oracle's 1.7 and 1.8 Java differ.
This could cause problems with creating a one-click Mac app that has the
proper stub to invoke Java.
Edward reported that the Apple 1.6 Vergil.app created by Ptolemy does
not work on his new Mac.
It is unfortunate that people still insist on using Windows and that
Windows has not kept up with the times. Why there would be limits in
the length of the classpath in this day and age is beyond me. One
possibility would be to look at how Eclipse handles the classpath.
Presumably, they have similar issues. However, that seems like extra work
Bottom line: we can go ahead with this, but it will result in some small
problems.

Hi Dan,
Requiring Java 7 seems reasonable, especially if you want to use features only
available in version 7. This will be for current development and the upcoming
2.5 release, correct?

I'd like to require Java 7 for Kepler. Java 7 has new features and
better performance, and Oracle is no longer publicly releasing security
updates for Java 6. Does anyone object to Kepler requiring Java 7?
For developers compiling Kepler, ant 1.8.2 or later is now required.
With the addition of new modules and jars, the class path has exceeded
the maximum path length on Windows. To avoid this problem, I've updated
the Kepler build system to use wildcards for the class path instead of
referencing individual jars. The earliest version of ant that supports
wildcards in the class path is 1.8.2.
