Subject [jira] [Updated] (PROTON-1939) NullPointerException while handing remote session.begin in TransportImpl
Date Fri, 21 Sep 2018 22:01:00 GMT

     [ https://issues.apache.org/jira/browse/PROTON-1939?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sreeram Garlapati updated PROTON-1939:
--------------------------------------
    Description: 
Our library (Microsoft Azure EventHubs java sdk) take a dependency on proton-j library for
AMQP implementation.

Many of Our customers are reporting this issue and would highly appreciate your response.

 

We are basically hitting this TODO in the TransportImpl.java - which results in reactor teardown:

[https://github.com/apache/qpid-proton-j/blob/master/proton-j/src/main/java/org/apache/qpid/proton/engine/impl/TransportImpl.java#L1160]

 

Here's the Exception stack trace:

 

{color:#24292e}com.microsoft.azure.eventhubs.impl.MessagingFactory$RunReactor.run:487 messagingFactory[MessagingFactoryab1d8d],
hostName[NNNNNNNNNNN.servicebus.windows.net], error[UnHandled exception while processing events
in reactor:{color}
 {color:#24292e} java.lang.NullPointerException: uncorrelated channel: 3{color}
 {color:#24292e} org.apache.qpid.proton.engine.impl.EventImpl.dispatch(EventImpl.java:112){color}
 {color:#24292e} org.apache.qpid.proton.reactor.impl.ReactorImpl.dispatch(ReactorImpl.java:324){color}
 {color:#24292e} org.apache.qpid.proton.reactor.impl.ReactorImpl.process(ReactorImpl.java:292){color}
 {color:#24292e} com.microsoft.azure.eventhubs.impl.MessagingFactory$RunReactor.run(MessagingFactory.java:462){color}

 

here's how to reproduce this error:
 * configure the listener - to delay respond to session.begins for ex: by 5 secs
 * then client (or another peer) sends session.begin
 * client doesn't receive any response even after 1 sec
 * then the client decides to close the session
 * then, after few sec's service(listener) responds back with session.begin

 Please contact us at [sreeramg@microsoft.com|mailto:sreeramg@microsoft.com] [sjkwak@microsoft.com|mailto:sjkwak@microsoft.com]
- if you need more data on this or need a resource to contribute to this. Truly appreciate
your help.
