    • Environment:
      mariadb connectorj 2.4.4, mariadb 10.2.19, java 8

      Description

      I have a client prepared statement for query "select timestampadd(HOUR, ?, '2019-10-10')"
      and set parameter as java Byte value '-6'.
      In result, a mariadb 10.2.19 executes next query "select timestampadd(HOUR, 0xFA, '2019-10-10')"
      Result of query is wrong because it has set wrong value for the parameter.

      I've debugged it a bit and see that org.mariadb.jdbc.internal.com.send.parameters.ByteParameter.java uses hex for text protocol. It seems that code is wrong and should rather be similar to IntParameter.java class code.
