Cassandra list<blob> read data incorrectly -

reading list , got wrong data.

create table tt (k text primary key, msg list<blob>);    static byte[] msg = new byte[] { 6, 6 }; static byte[] msg1 = new byte[] { 7, 7 };      preparedstatement upsert = session.prepare("update tt set msg = msg + ? k = ?");     session.execute(upsert.bind(collections.singletonlist(bytebuffer.wrap(msg)), key));      upsert = session.prepare("update tt set msg = msg + ? k = ?");     session.execute(upsert.bind(collections.singletonlist(bytebuffer.wrap(msg1)), key));      preparedstatement statement = session.prepare("select msg tt k = ?");     resultset rs = session.execute(statement.bind(key));     (bytebuffer bs : rs.one().getlist("msg", bytebuffer.class)) {         (byte b : bs.array())             system.out.print(b + ", ");         system.out.println();     } 

data stored correctly:

cqlsh:bellrock> select msg tt;   msg ------------------  [0x0606, 0x0707] 

but outputs as:

0, 0, 0, 2, 0, 0, 0, 2, 6, 6, 0, 0, 0, 2, 7, 7,
0, 0, 0, 2, 0, 0, 0, 2, 6, 6, 0, 0, 0, 2, 7, 7,

cqlsh:ks> show version [cqlsh 5.0.1 | cassandra 2.2.0 | cql spec 3.3.0 | native protocol v4] 

driver version: cassandra-driver-core 2.1.7.1

it turned out bug in driver cassandra-driver-core 2.1.7.1 works fine after put in earlier version 2.0.10.1
