PHP Notice:  Function _load_textdomain_just_in_time was called incorrect

 PHP Notice:  Function _load_textdomain_just_in_time was called <strong>incorrectly</strong>. Translation loading for the <code>math-captcha</code> domain was triggered too early.

// This warning fills up log file. 
// include_once(MATH_CAPTCHA_PATH . 'includes/class-core.php'); // This loads first.
// so , add_action('plugins_loaded', array($this, 'load_defaults')); // hits first

// And hook in wp-math-captcha.php, hits after.
add_action( 'plugins_loaded', array( $this, 'load_textdomain' ) );

// so moving below method to class-core.php will sort out this warning.
public function load_textdomain() {
		load_plugin_textdomain( 'math-captcha', false, MATH_CAPTCHA_REL_PATH . 'languages/' );
	}
// So please, move above method to class-core.php "plugins_loaded" hook and remove from wp-math-captcha.php
