> There is a potential risk of Long.MAX_VALUE overflow in the 
> sessionExpirationTimeNanos calculation within the SaslServerAuthenticator 
> class.
> Location:
>  !image-2025-08-01-10-12-04-784.png! 
> The calculation sessionExpirationTimeNanos = authenticationEndNanos + 1000 * 
> 1000 * retvalSessionLifetimeMs can potentially overflow when:
> retvalSessionLifetimeMs is very large 
> authenticationEndNanos is already a large value
> The multiplication 1000 * 1000 * retvalSessionLifetimeMs exceeds 
> Long.MAX_VALUE - authenticationEndNanos
