Hello Martin 

I use weld 2.4; I tested this in liberty and wildfly-10.1.0.Final

Regards

Hi Benjamin,

the lifecycle of @Dependent instances created through 
javax.enterprise.inject.spi.CDI is not well defined. So it's always 
better to destroy such instances when not needed. However, it would make 
sense to destroy such instances during shutdown.

I believe this works in Weld SE. What environment/runtime do you use?
