Wrong behavior when existing statename is used as guard on a transition

[BeckmaR]

When the user has
interface sensor:
in event measure

and a state named measure and then proceeds to use measure as transition guard (instead of sensor.measure), SCT goes in a loop in TypeInferrer until it finally throws a StackOverflowError in the console. After some time, the validation is done and SCT is usable again, but not showing an Error Marker.
The problem view only shows Error executing EValidator.

Steps to reproduce:

• Create new Statechart Model
• Create transition from StateA back to StateA
• In the transition guard, write StateA.

Also, SCT has no problem with the user declaring

internal:
    event StateA

We have a recursion after adding the shortcut method InferenceResult infer(EObject), in order to avoid calling InferenceResult infer(EObject, IValidationIssueAcceptor) with an null acceptor from outside. However "infer" just calls "inferTypeDispatch", which fallbacks to "infer" when no other implementation is found => Recursion
