The driver automatically falls back to the older v2 protocol when
necessary. It tries the v3 protocol initially, which is what produces
the "unsupported frontend protocol" error on the server side, and then
falls back to v2 when that fails.
Antonio, can you try to reproduce this with debug logging enabled (add
"?loglevel=2" to the end of your JDBC URL), and send me the resulting
debug output to me off-list?
