[jira] [Created] (AMQ-6677) NIO setup produces deadlock on add new subscriber

Eugene Nedzvetsky created AMQ-6677:
--------------------------------------

             Summary: NIO setup produces deadlock on add new subscriber 
                 Key: AMQ-6677
                 URL: https://issues.apache.org/jira/browse/AMQ-6677
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 5.14.5
         Environment: Windows 7 x64
            Reporter: Eugene Nedzvetsky


I reproduced this issue with NIO setup.
Steps to reproduce:
1. replace wrapper.conf and activemq.xml files(attached)
2. start Activemq in the console mode
3. install nodejs
4. unpack files from the archive deadlock.zip to some directory
5. execute npm.exe install stomp
6. execute nodejs suppliers.js and wait about 10 seconds
7. execute nodejs consumers.js and 20 seconds
8. open activemq console and type ctrl-break or kill -3 <actiemq-pid>
stop Activemq and reproduce steps 6 - 8 again if deadlock message doesn't exist.
