> Apparently WireFormatNegotiator checks only magic bytes during the
> format negotiation and does not check the version.
> So NMS client V2 talks to ActiveMQ V3.
> 394 [-1211205856] INFO Apache.NMS.Tracer (null) - SENDING:
> WireFormatInfo[ Magic=System.Byte[] Version=2
> MarshalledProperties={CacheEnabled=False, SizePrefixDisabled=False,
> StackTraceEnabled=False, TcpNoDelayEnabled=False,
> TightEncodingEnabled=False} ]
> 395 [-1225606256] DEBUG Apache.NMS.Tracer (null) - Parsing type: 1
> with: Apache.NMS.ActiveMQ.OpenWire.V1.WireFormatInfoMarshaller
> 403 [-1225606256] INFO Apache.NMS.Tracer (null) - RECEIVED:
> WireFormatInfo[ Magic=System.Byte[] Version=3
> MarshalledProperties={CacheEnabled=True, CacheSize=1024,
> SizePrefixDisabled=False, TightEncodingEnabled=True,
> MaxInactivityDuration=30000, MaxInactivityDurationInitalDelay=10000,
> StackTraceEnabled=True, TcpNoDelayEnabled=True} ]
> Please note that even though ActiveMQ claimed V3 protocol, NMS client accepted it.
> According to the current code in WireFormatNegotiator  only magic bytes are checked but
not the version.
