Now, let's see how you could use that to return a custom response.

Let's say that you want to return an <a href="https://en.wikipedia.org/wiki/XML" class="external-link" target="_blank">XML</a> response.

You could put your XML content in a string, put that in a `Response`, and return it:

          .put(ClassCastException.class, e -> e instanceof ClassCastException)
          .put(
              ConcurrentModificationException.class,
              e -> e instanceof ConcurrentModificationException)
          .put(ExecutionError.class, e -> e instanceof ExecutionError)
          .put(ExecutionException.class, e -> e instanceof ExecutionException)

        defaultSettings.put("onelogin.saml2.security.logoutrequest_signed", "false");
        defaultSettings.put("onelogin.saml2.security.logoutresponse_signed", "false");

        defaultSettings.put("onelogin.saml2.security.want_assertions_signed", "false");

          .put(IndexOutOfBoundsException.class, e -> e instanceof IndexOutOfBoundsException)
          .put(NoSuchElementException.class, e -> e instanceof NoSuchElementException)
          .put(NullPointerException.class, e -> e instanceof NullPointerException)
          .put(NumberFormatException.class, e -> e instanceof NumberFormatException)
          .put(RuntimeException.class, e -> e instanceof RuntimeException)

          .put(IndexOutOfBoundsException.class, e -> e instanceof IndexOutOfBoundsException)
          .put(NoSuchElementException.class, e -> e instanceof NoSuchElementException)
          .put(NullPointerException.class, e -> e instanceof NullPointerException)
          .put(NumberFormatException.class, e -> e instanceof NumberFormatException)
          .put(RuntimeException.class, e -> e instanceof RuntimeException)
