      Per this design discussion:

      https://mail.openjdk.java.net/pipermail/amber-spec-experts/2020-May/002161.html

      The consensus is that, at least until we revisit the topic, member classes of local/anonymous classes should not be allowed to use the 'sealed' modifier or to extend/implement a sealed class or interface.

      The sealed-classes-jls spec change document should be updated accordingly.
