I've stumbled on the same thing a few times... The problem is that the
compiler plugin settings only affect the Java language features, not
the standard library against which the code is compiled. So even if
you're restricted from using generics or other Java 5 features, all
the new methods, classes and interfaces in the standard library are
still available if you use Java 5 or higher to run Maven and thus
compile the code.

The best workaround to this problem that I've come across so far is to
create custom mvn4 and mvn5 scripts that start Maven with JAVA_HOME
set to Java 1.4 and Java 5 installations respectively. Then you just
need to use "mvn4 clean install" whenever compiling Jackrabbit trunk.

ACK, thanks.
