使用@Formula批注时出现休眠错误

Question

I have an entity and all my SELECT s 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.getSuffixedPropertyAliases(DefaultEntityAliases.java:151)

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 .
