При заходе игрока на сервер мой плагин делает SELECT запрос в базе данных и выдает ошибку
Данная ошибка, как я понял, вылетает при достаточно длительном отсутствии игроков на сервере
Перед запросами я всегда проверяю подключение, и если его нет то переподключаюсь.

[08:33:59 WARN]: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was 45,244,121 milliseconds ago. The last packet sent successfully to the server was 45,244,122 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.
