Hibernate error when I use @Formula annotation

I have an entity and all my SELECTs are working fine.

But now I'm trying to use @Formula

@Formula("(SELECT DESFILIAL FROM SESC.DAFILIAL WHERE CODFILIAL = 2 FETCH FIRST 1 ROWS ONLY)")
private String desfilial;

And that's causing an error on Hibernate:

java.lang.NullPointerException
    at org.hibernate.loader.DefaultEntityAliases.intern(DefaultEntityAliases.java:193)
    at org.hibernate.loader.DefaultEntityAliases.getSuffixedPropertyAliases(DefaultEntityAliases.java:151)
    at org.hibernate.loader.DefaultEntityAliases.determinePropertyAliases(DefaultEntityAliases.java:93)

    at org.hibernate.internal.SQLQueryImpl.list(SQLQueryImpl.java:156)
    at org.hibernate.internal.AbstractQueryImpl.uniqueResult(AbstractQueryImpl.java:890)

I already saw that problem on some forums, but any solution. Does anyone know why @Formula is causing that?

What version of Hibernate are you using? There is this link to a known bug with @Formula causing a NullPointerException.
