NPE with MariaDbDataSource when setLoginTimeout(0) has been called

Hi, I am receiving a NullPointerException when executing the following code with version 2.7.12 of the mariadb-connector-j driver. We are using 2.7.12 because we are using Aurora, which 3.x does not support. The docs for setLoginTimeout seem to indicate that 0 should be an accepted value.

    MariaDbDataSource ds = new MariaDbDataSource("jdbc:mariadb://host/db?user=user&password=password");

    ds.setLoginTimeout(0);

    try (Connection connection = ds.getConnection()) {

      Statement statement = connection.createStatement();

      statement.execute("SELECT 1");

    }

Stack trace:
