> {{ConsumerProtocol.deserializeAssignment}} / {{deserializeConsumerProtocolSubscription}} only re-wrap {{BufferUnderflowException}} as {{SchemaException}} and it can also throw{{{}RuntimeException{}}} and bypass the existing {{catch (SchemaException)}} blocks. When that happens the exception escapes.
> This change broadens four {{catch (SchemaException)}} blocks in {{{}GroupMetadataManager{}}}, one in {{{}ClassicGroup.computeSubscribedTopics{}}}.
