Sandeep Tamhankar commented on CASSANDRA-11464:
-----------------------------------------------
Random theory I came up with about this: I wonder if C* doesn't parse the
OPTIONS message properly because the stream-id is 8-bit (since I'm sending
v1/v2), not 16-bit as it is in v3/v4. I could imagine that causing a nasty
mis-parse that might confuse C* and keep it from responding.
> C* doesn't respond to OPTIONS request containing low protocol number

> Observed in Ruby and Python drivers: if you send an OPTIONS message to C* 3.4
> (though I believe this goes back to 3.0) with a protocol version of 1, C*
> doesn't send a response to the client. If you specify a high protocol version
> (e.g. 5), C* does correctly respond with a protocol error.
