Mikhail Kolesnikov commented on AMQ-6600:
-----------------------------------------
Such exception are very hard to reproduce... The root cause -- AMQ create
separate thread for controling each of connection:
{code:java}
public abstract class TransportThreadSupport extends TransportSupport
implements Runnable {
private Thread runner;
protected void doStart() throws Exception {
runner = new Thread(null, this, "ActiveMQ Transport: " + toString(),
stackSize);
{code}
In case of some problem with connection this thread try to set "closed" status
for connection and some times it happens *after* the *close* method called on
Session object from main thread.
Generally, such an exception means that connection is broken.
> cannot open connection to broker when JAR file is missing (and misleading
> error)

> Key: AMQ-6600
> URL: https://issues.apache.org/jira/browse/AMQ-6600
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker, JMS client
> Affects Versions: 5.14.3
> Environment: Broker: Remote on Windows Server 2012 R2 (IP:
> 172.23.60.19)
> Client: local on Windows 7 (IP: 10.29.15.133)
> Reporter: Daniel Held
> Priority: Minor
>
> While trying to send a Message, I get an Error: Cannot send, channel has
> already failed. However, it seems that this happens already during
> establishing the connection (see Stacktrace).
> As this is an rather old project, we do not use Maven (yet). It seems that a
> jar File is missing: hawtbuf-1.11.jar. Because i got no Classloading
> problems, i did not check this first. However, I wonder why it is not
> possible here to include some better error Message?
> Stacktrace on Client is as follows:
> javax.jms.JMSException: Cannot send, channel has already failed:

> Transport: tcp:///10.29.15.133:56578@61616
> What I'm doing here is:
> QueueConnectionFactory qcf = (some Spring Bean)
> QueueConnection qc = qcf.createQueueConnection();
> QueueSession qs = qc.createQueueSession(true, Session.AUTO_ACKNOWLEDGE);
