java.io.IOException: Last packet not finished

(Sorry, I can't speak english)

I'm trying to replace the mysql jdbc driver with mariadb jdbc driver 1.5.

In glassfish the connection pool is configured with

• Resource Type: javax.sql.ConnectionPoolDataSource
• Data Source Class Name: org.mariadb.jdbc.MySQLDataSource
• user: xx
• password: xxx
• characterEncoding: UTF-8 (missing this in mariadb)
• portNumber: 3306
• serverName: localhost
• databaseName: xxxx

Our over 400 integrations tests are running without errors with the mysql jdbc driver.
With mariadb the last 100 test fail with this exception:

```
