[hibernate-dev] ExtendedBeanManager

[Benjamin Confino]

Hello Yoann

Indeed I have tried that as an experiment, I got the following error when 
I did:

Caused by: java.lang.ClassCastException: Cannot cast class 
com.sun.proxy.$Proxy22 to interface 
javax.enterprise.inject.spi.BeanManager
        at java.lang.Class.cast(Class.java:2623)
        at 
org.hibernate.resource.beans.container.internal.CdiBeanContainerBuilder.fromBeanManagerReference(CdiBeanContainerBuilder.java:72)

That was more or less what I expected so I didn't think much of it at the 
time, but from your email it sounds like this isn't what you'd expect? 

If it helps I'm running with hibernate-core-5.4.1.Final.jar - I'm not sure 
what other info will help you but if you let me know I can send it over. 

Regards
Benjamin

Hello,

It's supposed to work as you described.

Have you tried making your class implement *only* ExtendedBeanManager?
It should have worked even if your class implements both, but there might
be a bug... As far as I know we only ever pass objects implementing either
BeanManager or ExtendedBeanManager, never both.
