That is not correct. In the 7+64 bit case the first 7 bits are simply a
flag that the following 8 bytes / 64 bits should read as an unsigned
integer and used as the length. Further, in this case the most
significant bit must be 0 so there are 63 bits for the length making the
maximum length 2^63 - 1 which, not accidentally, is Long.MAX_VALUE.
