Subject: agsXMPP.Xml.xpnet.InvalidTokenException
Hello Alex,

When I received below message from other client, the agsXMPP library is broken in parser process. I can not get any log error for debugging.
The lib forced OnStreamError in agsXMPP.Xml.StreamParser at line 211. Please confirm it.

RECV:

I sent this message to the MiniClient without any problems.
Maybe there is an unhandled error in your code which closes the connection, or the error is coming from another stanza.
Can you try to sniff the traffic with a network sniffer? You must connect without TLS or SSL then.

Thank you Alex.

I do sniffer but it did not expose useful info for me except report about XML is not recognized.
And it only show content under uft8 character map and binary format.

Sorry, from my previous post, the message has no problem in parser.
In Encoding code, at byteType(buf, off) process it return value 10 and its not match to any case so this exception InvalidTokenException(off)  is called.

In my code when Presence event incoming I changed status for RosterItem and request DiscoInfo for each of item.
If I commented out Disco request, the error has not been raised.
But the code work very well until I used other client to login to server. I also tried Psi and Spark, both can login to server.

How can I debug exactly this issue?

Best,

it looks like you receive invalid XML characters.

what is the value of buf? Which function in the parser code raises the exeption?

Sorry, I got busy for other task and I can not response you as soon.

Now previous data is deleted out of my DB so I couldn't know what data in buf? Really sorry.
If I got this problem again I will report to you.

try to catch the XML which passes the wire from the ClientSocket OnRead and OnWrite handlers (Socket Debug in MiniClient). They get raised before the XML gets processed by the XML parser.
I assume that you receive invalid XML which raises this exception.
