RFR: 8330462: StringIndexOutOfBoundException when typing anything into TextField [v22]

[Oliver Kopp]

> Fixes https://bugs.openjdk.org/browse/JDK-8330462.
> 
> If the parameter `maxLength` is larger than `Integer.MAX_VALUE - start`, then an addition of `start` to it leads to a negative value. This is "fixed" by using `Math.max` comparing the `maxLength` and `maxLength + start`.
