Spring Projects Issues

**[Rossen Stoyanchev](https://jira.spring.io/secure/ViewProfile.jspa?name=rstoya05-aop)** commented Starting with /app/greetings creates a potential gap, while starting with /topic/greetings creates a potential overlap. So you have to start receiving the latest first via /topic/greetings, then...

**[spencercw](https://jira.spring.io/secure/ViewProfile.jspa?name=spencercw)** commented Hi Rossen. I understand that, but there doesn't seem to be any way to reliably subscribe to the topic first under the default configuration where the thread pool...
