- Fix MDEV-16895 CONNECT engine's get_error_message can cause buffer
                 overflow and server crash with long queries
  ha_connect_cc: Update version.
    get_error_message: Remove charset conversion.
  modified:   storage/connect/ha_connect.cc

- Fix a server crash on inserting bigint to a JDBC table
  JDBConn::SetUUID:
    Suppress check on ctyp that causes a server crash because ctyp
    can be negative and this triggers an DEBUG_ASSERT on return.
  modified:   storage/connect/jdbconn.cpp

- Update jdbc.result
  mysql-test/connect/r/jdbc.result: Recorded to reflect a message change.
