jam is deprecated

I have seen some mailing list threads that suggest keeping Leopard builds around to be able to use Jam to build for backward compatibility.  I am not sure if I need to or should do this.  My program has a Java GUI which already uses an ant built on Linux.  I wanted Xcode to build me a nice little bundle though, so on Mac OS 10.5.8 I created a project with a Java Application target in Xcode 3.0.  With little headache, this built me a great litte *.app bundle that I transplanted to a 32-bit machine running Leopard using Java 1.5.  My Java GUI requires 1.6 features, so the first thing the app does is check which version of JVM launched it and then try to display a helpful message about why you need Java 1.6 and where you ought to get it from.

What I read in an earlier thread was that I need the Leopard build to be able compile for a target JVM of 1.4 or 1.5 so that my program can display a useful message instead of allowing the command line to throw out a bunch of Java exceptions that don't mean anything to non-Java-programmers (including me).  Did I understand that correctly?

My colleague only has Snow Leopard, so he cannot build my Java GUI from the project without converting the targets.  If he converts them, will they still work for me in Leopard?  Are we looking at an unending wellspring of issues with some developers on Leopard and some developers on Snow Leopard?

Thanks,

Xochitl
