Re: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

This is the most annoying problem with MySQL I have come across so far. autoReconnect parameter surely doesn't help. If you are using a DataSource, using validationQuery="select 1" is said to help but I am not sure.

If you search online, this is the most commonly reported issue with MySQL and someone from Oracle should put down a proper solution for this and make it a sticky.
