Andrei Gheorghe commented on AMQCPP-532:
----------------------------------------
Sometimes it doesn't crash and sometimes it takes a while ( sometimes a few
minutes ). There are two ways it can crash and I've attached both stacktraces.
> Frequently deleting queue browser causes access violation

> Key: AMQCPP-532
> URL: https://issues.apache.org/jira/browse/AMQCPP-532
> Project: ActiveMQ C++ Client
> Issue Type: Bug
> Affects Versions: 3.8.2
> Environment: Windows
> Reporter: Andrei Gheorghe
> Assignee: Timothy Bish
> Attachments: crash.cpp, stacktrace.txt
>
>
> The following code should reproduce this issue :
> #include <activemq/library/ActiveMQCPP.h>
> #include <activemq/core/ActiveMQConnectionFactory.h>
> #include <activemq/commands/ActiveMQQueue.h>
> using namespace cms;
> int main()
> {
> try
> {
> activemq::library::ActiveMQCPP::initializeLibrary();
> activemq::core::ActiveMQConnectionFactory connectionFactory(
> "tcp://localhost:61616" );
> auto connection = connectionFactory.createConnection();
> connection->start();
> auto session = connection->createSession( Session::SESSION_TRANSACTED );
> activemq::commands::ActiveMQQueue queue( "testqueue" ); //sometimes it
> doesn't crash if the queue is empty so it should have atleast a message
> while ( 1 )
> {
> auto queueBrowser = session->createBrowser( &queue, "" );
> auto enumeration = queueBrowser->getEnumeration();
>
> if ( enumeration->hasMoreMessages() )
> auto message = enumeration->nextMessage();
> delete queueBrowser;
> }
> }
> catch ( const std::exception& e )
> {
> std::string what = e.what(); //sometimes it throws an exception
> like "Monitor is still in use!"
> }
> while ( 1 ) {} //wait, sometimes an activemq thread fails
> }
