Issue with org.mariadb.jdbc.MySQLConnection.setNetworkTimeout

Hi there,

We were seeing an issue while using MariaDB 1.1.7 and HikariCP (2.2+) together

I filed a bug here - https://github.com/brettwooldridge/HikariCP/issues/175

Below is a snippet from the conversation from the above github link

Regards

==========================

We will implement a workaround for this, but the issue seems to be caused by a bug in the MariaDB driver.

We call connection.getNetworkTimeout() to determine whether network timeout is supported. If network timeout is not supported, we expect a SQLFeatureNotSupportedException exception (like above) from this call. However, connection.getNetworkTimeout() is simply returning the value 0. Therefore, we are expecting that timeout is supported. Subsequently, we call connection.setNetworkTimeout() and at this point a SQLFeatureNotSupportedException is thrown.

MariaDB, if it does not support setNetworkTimeout() should also throw SQLFeatureNotSupportedException for getNetworkTimeout(). Please open a bug against the MariaDB JDBC driver. As I said, we will implement a workaround, but this is improper behavior from their driver.
