Destroying a consumer may cause a crash
---------------------------------------
Key: AMQCPP-361
URL: https://issues.apache.org/jira/browse/AMQCPP-361
Project: ActiveMQ C++ Client
Issue Type: Bug
Components: CMS Impl
Affects Versions: 3.2.5
Environment: all
Reporter: Teemu Torma
Assignee: Timothy Bish
ActiveMQSessionExecutor::dispatch gets a consumer and calls consumer's dispatch
method without holding any locks in between. This leaves a window when a
consumer can be no longer valid on a dispatch call causing a crash.
Since this is a timing issue it is hard to demonstrate as such. If one adds
let's say one second sleep in ActiveMQSessionExecutor::dispatch before the call
to the consumer->dispatch, and destroys a consumer on a destination which has
messages incoming will likely crash the application.
