Description

in cassandra 3.5 i get the following exception when i run this cqls:

--DROP KEYSPACE bugtest ;
CREATE KEYSPACE bugtest
 WITH REPLICATION = { 'class' : 'SimpleStrategy', 'replication_factor' : 1 };
use bugtest;
CREATE TYPE tt (
	a boolean
);
create table t1 (
	k text,
	v map<text,frozen<tt>>,
	PRIMARY KEY(k)
);
insert into t1 (k,v) values ('k2',{'mk':{a:false}});
ALTER TYPE tt ADD b boolean;
UPDATE t1 SET v['mk'] = { b:true } WHERE k = 'k2';
select * from t1;  

the last select fails.
