Derby

db driver maven dependency

MySQL

MySQL throws an EOFException when the database connection has been closed after the lease has expired, but it works again on subsequent requests.

There is a reported issue with DBCP and the MySQL driver. Check the JIRA issue for more info and a possible solution
