AuthenticationException
class AuthenticationException extends RuntimeException
Authentication failed: who the caller is could not be established.
Every class in this hierarchy takes an optional message, another exception whose message it reuses, or nothing at all. isException recognises all of them; a plain Error is not one.
Examples
Throwing and catching
throw new AuthenticationException("something specific about this call");
try {
doWork();
} catch (error) {
if (error instanceof AuthenticationException) {
// handled
}
}
