public class UtilCompatibleJdk14 extends Object implements UtilCompatible
UtilCompatible
which runs in
JDK 1.4.
The code uses JDK 1.5 constructs such as generics and for-each loops,
but retroweaver can convert these. It does not use
java.util.EnumSet
, which is important, because retroweaver has
trouble with this.
