BatchLinkableResourceStorageWritable error when using K3 and xtend 2.27

dvojtise commented 2 years ago

Bug description

in latest version of GEMOC 3.6.0 (based on Eclipse 2022-06, xtend 2.25) a lot of error messages occurs in the Default messagingSystem console and the Error Log view

org.eclipse.xtext.xbase.resource.BatchLinkableResourceStorageWritable  - Object (JvmParameterizedTypeReference: java.lang.String) is not contained in any resource

The code seems to works but isn't comfortable for the user

Apparently this wasn't the case with the previous version of the studio based on Eclipse 2021-12 (xtend 2.27)

The Xtend active annotation of K3 is the same (same version of K3 in both GEMOC installations)

Expected behavior

no error message in the console or the Error log when working with K3/Xtend projects.

How to reproduce

Steps to reproduce the behavior:

install the K3 example, Hello ecore (k3 plugin)
Simplify the aspect as follow
```
package hello_ecore
```

import org.eclipse.emf.ecore.EPackage import fr.inria.diverse.k3.al.annotationprocessor.Aspect

import static extension hello_ecore.EPackageAspect.* import org.eclipse.emf.ecore.EClassifier

@Aspect(className=EPackage) class EPackageAspect { String foo }

@Aspect(className=EClassifier) class EClassifierAspect { }


3. See error in Error log and console

Possibly related to https://github.com/eclipse/xtext-extras/issues/695 (some changes have been introduced in xtend 2.26 that look to be related to that message)
