decode something maybe t1 or t2 PooledUnsafeDirectByteBuf(ridx: 0, widx: 22, cap: 1024)
T2Packet{id=257, value=12, name='t2 message'}
encode type 2 T2Packet{id=257, value=13, name='t2 answer t2 message'}
decode something maybe t1 or t2 PooledUnsafeDirectByteBuf(ridx: 0, widx: 18, cap: 1024)
redirect message, because its t1
t1 decoding! PooledUnsafeDirectByteBuf(ridx: 0, widx: 18, cap: 1024)
T1Packet{id=1, name='t1 message'}
sending t1....
