Compilation error in generated static entity view metamodel in case of singular Map

[Mobe91]

Description

Given the following entity view

@EntityView(MyEntity.class)
interface MyView {
  @MappingSingular
  Map<String, String> getSingularMap();
}

Generating a metamodel for this view using blaze-persistence-entity-view-processor results in invalid Java code that fails compilation.

More precisely, the following is generated:

public AttributePath<T, Map<String java.lang.String>, Map<String java.lang.String>> singularMap() {
    MethodSingularAttribute<ContainerTemplateDto, Map<String java.lang.String>> attribute = LocationOverviewContainerDtoImplContainerTemplateDto_.externalReferences;
    return attribute == null ? getWrapped().<Map<String java.lang.String>>get("singularMap") : getWrapped().get(attribute);
}

Expected behavior

Valid metamodel code is generated.

Actual behavior

The generated metamodel code does not compile.
