Created attachment 174403 [details]
grammar producing the IllegalArgumentExceptions

Using the attached grammar I started a runtime-Eclipse and created this example model (file also attached):

type modificationDate mapped-to java.util.Date
interface myAggregation mapped-to java.util.Collection

As soon as you insert a new line "type fooBar mapped-to " between the lines above a lot of IllegalArgumentExceptions appear in the console of my workspace-Eclipse. The attached example already contains this additional line and will produce the exceptions as soon as the editor is opened. This is the head of the first IAE that's reported:

java.lang.IllegalArgumentException: interface myAggregation
