You can just switch-match on trusted types, then it even looks modern. :)

I am still afraid of such a pattern in the future like:

CharSequence cs = ...
if (cs.getClass().getModule() == Object.class.getModule()) {
// or cs.getClass().getClassLoader() == null
cs.getChars(...);
} else {
// damn, can't trust an arbitrary char sequence!
char[] intermediate = ...
cs.getChars(...);
// copy from intermediate etc.
}
