Conflicting handlers for Gradle Tasks Quick Launcher

Trying to open the Gradle Tasks Quick Launcher in Eclipse results in the following error:

I could reproduce the problem. However, it doesn't prevent you from opening the Quick Tasks Launcher, correct? The CA works as expected as well, right?
The issue is that the tasks viewer object is built by Quick Tasks Launcher and the "Gradle Build" External Tools Launch config wizard. The same id handler for CA is registered in both cases, hence you get a message in the log. I think it's worth putting this as a bug report in Gradle Eclipse JIRA https://issuetracker.springsource.com GRADLE component. Think the priority for this is minor since it doesn't block the workflow... at least it doesn't cause any harm really from I've seen (please correct me if I'm wrong)

P.S. I could only reproduce this when i pinned the quick tasks launcher (left it opened all the time) and then attempted to open the "Gradle Build" External Tools launch config wizard. How do you reproduce it?
