Affects: 5.2.0.RELEASE

I'm working on a Spring Boot project where the SpEL compilation is enabled through a WebMvcConfigurer:

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {
    @Autowired
    private ITemplateResolver templateResolver;
    @Bean
    public SpringTemplateEngine templateEngine() {
        SpringTemplateEngine templateEngine = new SpringTemplateEngine();

        templateEngine.setEnableSpringELCompiler(true);

        // ...
        templateEngine.setTemplateResolver(templateResolver);
        // ...

        return templateEngine;
    }
}

I got a VerifyError when using an expression in some Thymeleaf views, where I try to invoke a method on an object:

                        <td>
                                <!-- here we display some field values of the item -->
                        </td>
                        <td>
                                <!-- here we want to check if the item may be edited by the current user, which was put in the model -->
                        	<span th:if="${item.isEditable(user)}">
                                       <!-- here we build a link to edit the item -->
                        	</span>							
                        </td>
                    </tr>
                    </tbody>
                </table>
    </body>
</html>

Here is the stacktrace for the error:

It appears that the error occurs because the method isEditable is defined this way:

public class Item implements Editable {
    // some fields
    private String someField;

    // some getters and setters

   @Override
   public boolean hasSomeProperty() {
       return someField != null;
    }
}
public interface Editable {
   default boolean isEditable(User user) {
        return user.isAdmin() && hasSomeProperty()
   }

   boolean hasSomeProperty();
}

Actually, when the method is defined this way, the expression compilation works nicely:

public class Item extends AbstractEditable {
    // some fields
    private String someField;

    // some getters and setters

   @Override
   public boolean hasSomeProperty() {
       return someField != null;
    }
}
public abstract class AbstractEditable {
   public boolean isEditable(User user) {
        return user.isAdmin() && hasSomeProperty()
   }

   public abstract boolean hasSomeProperty();
}
