Because Hudson compiles with Java 1.5 or even 1.6. Setting -source and
-target to 1.4 in javac does not help, if you are using methods/classes. The
java compiler only checks syntax and creates 1.4 classes. But for compiling
and checking it uses the builtin rt.jar (which is newer).

If you want strict 1.4 checking, you must set the bootclasspath to an old
rt.jar from 1.4 or just 1.4 at all for compiling.
