Seems that it might be possible with this to start using some 1.5

Be *very* careful about what 1.5 language features you start using in
your code. It's not as easy as specifying -source 1.5 -target 1.4 to
get a 1.4 compatible class/jar.
If you end up using the "wrong" language constructs in your code, you
will become dependant on additional libraries like Retrowaver (or
similar) that implements the missing features/classes for you.
To be clear I explicitly meant Java language constructs (ie. JLS), not
1.5 new methods or classes. As Bryan said if you could share your
experience that would be helpful.
Never mind:
> $JAVA_HOME/bin/javac -target 1.4 -source 1.5
javac: source release 1.5 requires target release 1.5
