Telling people to say "you must declare a java version" is no big deal; 
its easily done. But there are a lot of projects out there that built 
happily, and which now dont because gump upgraded.

Furthermore, what if we can't upgrade them all? There are old projects 
out there that havent had a change for 12+ months, but which still work. 
Its only that they dont compile on java1.5.

if we the properties ant._internal._javac.source and that set the defaults for javac, then you 
can also use them on the command line to build anything 'legacy', 
without touching the build file.
