18 * The CONSTANT_Long_info and {@link CONSTANT_Double_info} represent eight-byte
19 * numeric (long and double) constants.<P>
20 *
21 * The unsigned high_bytes and low_bytes items of the CONSTANT_Long_info structure
22 * together contain the value of the long constant
23 * (( long ) high_bytes << 32) + low_bytes , where the bytes of each of high_bytes
24 * and low_bytes are stored in big-endian (high byte first) order.
