public class ProtocolError extends CoordinatorException
Protocol errors indicate that the client triggered a protocol violation (for instance, a
QUERY
message is sent before a STARTUP
one has been sent). Protocol errors should
be considered as a bug in the driver and reported as such.
This exception does not go through the RetryPolicy
, it is always rethrown directly to
the client.

@NonNull public DriverException copy()
DriverException
This returns a new exception, equivalent to the original one, except that because a new object is created in the current thread, the top-most element in the stacktrace of the exception will refer to the current thread. The original exception may or may not be included as the copy's cause, depending on whether that is deemed useful (this is left to the discretion of each implementation).
This is intended for the synchronous wrapper methods of the driver, in order to produce a more user-friendly stack trace (that includes the line in the user code where the driver rethrew the error).
