As the output of toGenericString does not attempt to fully capture the full declaration information of a class or interfaces, omitted any extends or implementation information for example, I think it is fine to also omit any listed of permitted subtypes for a sealed class or interface. This sidesteps design issues around which permitted subtypes should be filtered out for display purposes, etc.

CSR up for review: https://bugs.openjdk.org/browse/JDK-8322969
