timeout while waiting on advertised authentication mechanisms

[Former user]

Hi, I got an error when I run my code with ibm jdk 8.0，but it works with Oracle JDK 1.8. I connect the Cisco xmpp server with socket connection. PS.the babbler version is 0.8 the error message below

The Anonymous is me . Actually, I think the issue caused by tls. Maybe it's different between Oracle and IBM

[Ran Ji]

Anybody here？is it possible that IBM JDK doesn't support starttls ?

Hi Ran Ji,

I am here. But unfortunately I have currently little time to investigate your problem with IBM JDK.

With Oracle JDK or OpenJDK there's no issue.

Anyway, I think you are right, it's probably some kind of TLS issue.

Maybe you can try to find the cause?

Thank you for your help. The class XmppStreamReader ,Line 116, when it calls createXMLEventReader method , ibm jdk can't handle the inputstream, and no error message on the console. I'll try my best.
