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.
}
