Jesper - these errors or at least the one about scanner being disabled matches what is/was found at https://issues.jboss.org/browse/JBIDE-11215 (verified bug in EAP 5.x family).
The other two weird errors here is the string/boolean cast - that should not happen and we should get that investigated.
Unfortunately just starting today AS tooling master is on PTO so it might be a week before we can digg deep.
