I'm very sure that there are incompatibilities with bytecode outputted
by the 1.4 compile which makes problems running it on 1.3. Because of
that, at one point I built a Turbine release (2.3) with both 1.3 and 1.4
jars.
The problem is documented in the Java bug database, but I'm not able to
find a reference to it. There should be something about it on the
turbine-dev archive around the time of the 2.3 release, but I don't know
whether the archives work again.
I've pointed to this problem a long time ago but it got largely ignored,
mainly because everyone here seems to compile their jars themselves. But
I did have the problem with maven (when I was still using 1.3 as my main
platform) binary relases, which were built with JDK 1.4 (1.4.1 IIRC) and
did not run on the Sun 1.3.1 JRE.
IMHO this will get worse with 1.5.
