-------------------------------------------------------------
I tried to add the lock that I have suggested to
ActiveMQConnection::cleanup(), repeated the test a few times, and did not get
the same crash as before. So that might have worked. However, I got another
crash in ActiveMQConnection::onException() after the cleanup() call. The error
message was: R6025 -pure virtual function call. Could you please take a look?
Thanks!

It looks like the connection can be deposed/deleted by another thread while a
thread is in the onException() function.

> On the call stack, we saw that following function from class
> decaf::lang::Exception was called:
> void Exception::buildMessage( const char* format, va_list& vargs ) {
> // Allocate buffer with a guess of it's size
> AprPool pool;
> // Allocate a buffer of the specified size.
> char* buffer = apr_pvsprintf( pool.getAprPool(), format, vargs );
> // Guessed size was enough. Assign the string.
> message.assign( buffer, strlen( buffer ) );
> }
> The first parameter passed into apr_pvsprintf was NULL, causing the crash.
> Could you please take a look and see if there is any bug in the activemqcpp
> code that could cause the problem. Thanks!
