        * java/lang/Boolean.java (Boolean(String)): Set Value' to false on a
        null String constructor parameter.
        * java/net/natPlainSocketImpl.cc: Remove unneccessary sprintf calls
        for exception messages.
        BooleanClass: declare.
        (setOption): Use BooleanClass instead of Class.forName() for
        instanceof test.
        (bind): Cast 4th parameter of setsockopt to char *' for
        compatibility with older Solaris headers.
        * java/net/natPlainDatagramSocketImpl.cc: Remove unneccessary
        sprintf calls for exception messages.
        BooleanClass, IntegerClass: declare.
        (setOption): Use BooleanClass and IntegerClass, not Class.forName()
        for instanceof test.
