-			When lombok generates a null-check <code>if</code> statement, by default, a <code>java.lang.NullPointerException</code> will be thrown with '<em>field name</em> is marked @non-null but is null' as the exception message. However, you can use <code>IllegalArgumentException</code> in this configuration key to have lombok throw that exception with this message instead. By using <code>Assertion</code>, an <code>assert</code> statement with the same message will be generated.
