your bootstrap class actually loaded, so it looks like it's one of your other
classes ... In particular, I suspect your Application class is built 1.6, since
it's failing on the first defineClass call.
unjar your application jar and run
find . -name '*.class' -exec file {} \; | grep 50
I would add a source and target declaration to your wocompile step in
build.xml, or pass in -source and -target to ant. I don't think ant building,
even from eclipse, cares about your JDK setting.
