Unfortunately, this will not work using Sun's compiler.  Use of the
"-target 1.4" option requires the use of the "-source 1.4" option.  This
means that you cannot target 1.4 if there are any 1.5 language features
in the source, such as annotations or generics.

For example, try compiling this class:

public class Test {
  @Override public String toString() { return "test"; }
}

If you run "javac -target 1.4 Test.java", it fails with an error
message, as does "jaac -source 1.5 -target 1.4".  And, of course, "javac
-source 1.4 -target 1.4" fails with a compile error.

I wonder if other compilers are as strict.
