Math.toIntExact why only long?

[Raffaello Giulietti]

The plan is to use the facilities described in "JEP 488: Primitive Types 
in Patterns, instanceof, and switch (Second Preview)" once they become a 
permanent _language_ feature.

Currently, you can perform one of the tests provided in 
https://docs.oracle.com/en/java/javase/23/docs/api/java.base/java/lang/runtime/ExactConversionsSupport.html, 
and then safely cast if the test succeeds.

But I suggest to rather wait for the JEP to become permanent, as it 
integrates much more elegantly with the ongoing "pattern" work and the 
rest of the language. You can enable preview features in JDK 23 if you'd 
like to get a feeling.
