Hi Filipe
Yes we changed ClientPreparedQueryBindings to ServerPreparedQueryBinding and solved above problem.

I want to ask another question.

first we want to do following code optimization.

ThreadLocal<Calendar> calendar = ThreadLocal.withInitial(() -> Calendar.getInstance(US));

ResultSet rs = stmt.executeQuery();
byte[] bytes = rs.getBytes(column);
java.util.Date date = toDate(bytes, calendar.get());

if directly invoke rs.getDate(column, calendar.get());
we found that getDate method internally invoked calendar.clone(); we want to avoid that clone invocation.

but we can't ensure the protocol type of `bytes` object, it might be text protocol or binary protocol.
for now we write a method to get protocol type

public boolean isBinary(ResultSet v) throws SQLException {
return (v != null) && (v.getStatement() instanceof PreparedStatement);

I want to ask is there a easy way to get the protocol type or specify client protocol type?
