I use maven on 1.4.2 all the time. It looks like your system is reporting the wrong java spec version. Look at the source:

        if ( "1.4".compareTo( System.getProperty( "java.specification.version" ) ) > 0 )
        {
            System.err.println( "Sorry, but JDK 1.4 or above is required to execute Maven. You appear to be using "
                + "Java:" );
            System.err.println( "java version \"" + System.getProperty( "java.version", "<unknown java version>" )
                + "\"" );
            System.err.println( System.getProperty( "java.runtime.name", "<unknown runtime name>" ) + " (build "
                + System.getProperty( "java.runtime.version", "<unknown runtime version>" ) + ")" );
            System.err.println( System.getProperty( "java.vm.name", "<unknown vm name>" ) + " (build "
                + System.getProperty( "java.vm.version", "<unknown vm version>" ) + ", "
                + System.getProperty( "java.vm.info", "<unknown vm info>" ) + ")" );

            return 1;
