Xtext: super.getScope causes StackOverflowError

Question

When I call "compile(ResourceSet rs, IAcceptor acceptor)" with the code in my DSL, I got StackOverflowError. I believe "super.getScope" causes that. I don't get any error with the same code on tests via "Launch Runtime Eclipse". Any suggestion?

Thanks in advance.

override getScope(EObject context, EReference reference) {
    if(reference === MyDslPackage.eINSTANCE.referenceHandle_Ref){
        return scopeForReferenceHandle(context)
    }
    switch(context){
        
        Composer        : return delegate______Scope(context,reference)
        Closure         : return delegate______Scope(context,reference)
        FieldSelection  : return delegate______Scope(context,reference)
    }
    return super.getScope(context, reference) 
}
