Increment fails on simple test
Hi All,
Surely, I'm doing something wrong here!

Increment expects a long as per returned by Bytes.toBytes(long). ie:
8 bytes, big endian.
you put '1' array length 1.
when increment finds no value, it assumes '0'. if you want 0 based
counting dont put an initial value.
