Nathan Mittler commented on AMQCPP-59:
--------------------------------------
could you include the source code for the application that exhibits this
behavior?
> Exception is thrown when destroying consumer after connection failure
> ---------------------------------------------------------------------
>
> Key: AMQCPP-59
> URL: https://issues.apache.org/activemq/browse/AMQCPP-59
> Project: ActiveMQ C++ Client
> Issue Type: Bug
> Affects Versions: 2.0
> Reporter: Albert Strasheim
> Assigned To: Nathan Mittler
> Fix For: 2.0

>
> Brought over from AMQCPP-46.
> In a program that reconnects when it detects a connection failure using an
> exception listener, there seem to be two different places where exceptions
> can originate.
> In most cases when I shut down the broker and the exception listener fires
> properly and I can clean up everything (without deletes throwing exceptions),
> the stack trace that gets printed on the console looks like this:
> {noformat}
> WARNING: activemq::io::SocketInputStream::read - The connection is broken

> The message is printed twice with different tids, from the two threads that
> are active.
> Sometimes when I shut down the broker and the exception handler fires and I
> clean up everything but then the consumer's destructor throws an exception.
> In that case, the stack trace that is printed looks like this:
> {noformat}
> WARNING: activemq::io::SocketInputStream::read - An existing connection was
> forcibly closed by the remote host.

> Again I see this message from both threads. Note the slightly different line
> numbers in SocketInputStream.cpp and the slighty different error message
> (this is on Windows XP SP2). In this case the failure of the socket is
> probably being detected in a slightly different place.
> If the socket failure happens in the second way, it seems that destructors of
> consumers (and possibly producers and sessions) don't properly catch the
> exception when being destroying, causing their destructors to throw an
> exception, which isn't what we want.
