CDI.current() is not destroyed
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?

Hello
I have a servlet that acquires two instances of a dependent scoped bean.
The first is aquired by @Inject Instance<CdiBean> the second is
acquired
via CDI.current().select(CdiBean.class).get().
I can see that the first instance's @PreDestroy is called when I shut
down the application. However @PreDestroy is not called on the instance
acquired CDI.current. Here is the source:
My question is, is this behaviour intentional? And if it is, can you
please link me to the appropriate part of the spec that says when we
should expect a @Dependent bean created by CDI.current to be destroyed?
I have a customer concerned about this causing a potential memory leak.
Regards
Benjamin
