The difference is that java.version will return things like 1.4.2_08
instead of just 1.4, so they are not equivalent. ant doesn't offer a lot
of tools to parse such a string, the best you could do would be a global
substring match. Trying to find 1.4 would match 1.1.4 as well as 1.4.2
though. Since we don't support 1.1 builds we could do this, but it seems
a little fragile with perhaps other vendors using different format
strings. The best solution for older ant users might be to duplicate the
checks ant makes for ant.java.version in our own build file. That way we
can put in the latest updates and not require an upgrade.
