                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8813

            Reporter: Chhavi Gangwal


java.lang.IllegalArgumentException: null at java.nio.Buffer.limit(Buffer.java:267) ~[na:1.7.0] 	at org.apache.cassandra.utils.ByteBufferUtil.readBytes(ByteBufferUtil.java:543) ~[cassandra-all-2.1.2.jar:2.1.2] 	at org.apache.cassandra.serializers.CollectionSerializer.readValue(CollectionSerializer.java:122) ~[cassandra-all-2.1.2.jar:2.1.2] 	at org.apache.cassandra.serializers.MapSerializer.deserializeForNativeProtocol(MapSerializer.java:99) ~[cassandra-all-2.1.2.jar:2.1.2] 	at org.apache.cassandra.serializers.MapSerializer.deserializeForNativeProtocol(MapSerializer.java:28) ~[cassandra-all-2.1.2.jar:2.1.2] 	at org.apache.cassandra.serializers.CollectionSerializer.deserialize(CollectionSerializer.java:48) ~[cassandra-all-2.1.2.jar:2.1.2] 	at org.apache.cassandra.db.marshal.AbstractType.compose(AbstractType.java:66) ~[cassandra-all-2.1.2.jar:2.1.2]

The issue mainly occurs due to forced readBytes function in CollectionSerializer with version 3 for all collection types as well as UDT
