JPACrud.createCriteriaByExample does not work as expected

[cassiobastos]

No demoiselle 2.3.1, a classe JPACrud implementa o seguinte método:

private CriteriaQuery createCriteriaByExample(final T example) { final CriteriaBuilder builder = getCriteriaBuilder(); final CriteriaQuery query = builder.createQuery(getBeanClass()); final Root entity = query.from(getBeanClass());

final List predicates = new ArrayList(); final Field[] fields = example.getClass().getDeclaredFields();

for (Field field : fields) { if (!field.isAnnotationPresent(Column.class) && !field.isAnnotationPresent(Basic.class) && !field.isAnnotationPresent(Enumerated.class)) { continue; }

Object value = null;

try { field.setAccessible(true); value = field.get(example); }

catch (IllegalArgumentException e) { continue; } catch (IllegalAccessException e) { continue; }

if (value == null) { continue; }

final Predicate pred = builder.equal(entity.get(field.getName()), value); predicates.add(pred); }

return query.where(predicates.toArray(new Predicate[0])).select(entity); }

No trecho em negrito, poderia ser incluída a anotação JoinColumn.
