xtext: Domainmodel example: endless loop while opening the Association Hierarchy view

Step to reproduce:

Import the DomainModel Example shipped with the Xtext framework.
In the runtime Eclipse, create a java project with the following test.dmodel file:

import java.util.List

entity Blog {
	title: String
	posts: List<Post>
	
	op addPost(Post post) : void {}
	op getPosts() : List<Post> {}
}

entity HasAuthor {
	author: String
	
	op getAuthor() { author }
	op setAuthor() : void {}
}

entity Post extends HasAuthor {
	title: String
	content: String
	comments: List<Comment>
}

entity Comment extends HasAuthor {
	content: String
}

Place the cursor into the Comment entity and try to open the Association Hierarchy view. The following error appears in the console of the host eclipse:

Seems there is a problem with the Guice Bindings.

when chaning the code to

class OpenAssociationHierarchyHandler extends AbstractOpenHierarchyHandler {

	static val HIERARCHY_VIEW_PART_ID = 'org.eclipse.xtext.example.domainmodel.ui.editor.AssociationHierarchy'

	@Inject
	extension IGlobalServiceProvider

	@Inject
	EditorResourceAccess resourceAccess
	
	@Inject
	AssociationHierarchyBuilder b;

	override protected getHierarchyViewPartID() {
		HIERARCHY_VIEW_PART_ID
	}

	override protected createHierarchyBuilder(EObject target) {
		val xtextCallHierarchyBuilder = b

it works fine

the current

SharedCommonTypesResourceServiceProvider(DefaultResourceServiceProvider).get(Class<T>) line: 74	
IGlobalServiceProvider$ResourceServiceProviderImpl.findService(URI, Class<T>) line: 53	
IGlobalServiceProvider$ResourceServiceProviderImpl.findService(EObject, Class<T>) line: 64	
OpenAssociationHierarchyHandler.xtend line: 36	
AbstractOpenHierarchyHandler.xtend line: 49

leads to gazilliions of missing bindings e.g. for TypesFactory ands IScopeProvider
