Unknown MsgClass
What do these mean
Can you please suggest how to handle these? I am using version
<dependency>
<groupId>reuters</groupId>
<artifactId>upa</artifactId>
<version>8.0.0.L1.all.rrg</version>
</dependency>
I see that this is called inside Decoders.java and there is a switch block
static int decodeMsg(DecodeIterator iterInt, Msg msg)
try
{
decodeMsgHeader(iter, msg);
}
catch (Exception e)
{
return CodecReturnCodes.INCOMPLETE_DATA;
}
and inside this decodeMsgHeader is where I think this Unknown Class is being printed in default switch case
default:
System.out.println("Unknown msgClass: " + msg.msgClass());
assert (false);

It seems that the UPA is unable to decode those buffers because those contain invalid message classes.
To verify this issue, you may need to print the hex strings of those buffers.
You can use the code from Stack Overflow to convert a byte array to a hex string.
int position = buffer.data().position();
byte[] b = new byte[buffer.data().remaining()];
buffer.data().get(b);
System.out.println(bytesToHex(b));
buffer.data().position(position);0
