Pavol Srna confirmed he has seen this and he, too, has no clue as to what causes this.

Now, when I stopped the remote EAP 6.2 in my workspace, I got 2 more of these errors in the error view. Then I stopped a local EAP 6.2 instance, but that didn't show errors.

> Unfortunately I don't have much information here. I don't know what triggers this. It happened today when I verified some JIRAs in JBDS. I have AS 5.1, WildFly 8, EAP 6.2 and another remote EAP 6.2 set up in the workspace. Only one project - Java EE Web project from Central. 
> I started the different servers, deployed, undeployed etc. And then did nothing for maybe 1 hour. When I came back to look at Eclipse, I saw there was this exception in the error log.
> The thing is that this happened to me last week in different installation and different set of actions, but since it was too random, I didn't report a JIRA then. Now it's the second time, so I'm reporting a JIRA - perhaps somebody has seen the same?
