JIRA: https://jira.spring.io/browse/INT-3580 * Uncomment `org.springframework.integration.ip` category for the IP tests `log4j.properties` * Since all tests in the `StompIntegrationTests` uses the same application context and therefore the same `SubscriptionRegistry` the `waitForSubscribe()` should wait exactly for that `subscription` in which it is interested in. The previous fix wasn't enough
