Thank you for your response! I understand that this is essentially an integration issue.

Btw, it seems that WeldInitialListener considers the case that injection is disabled.
It has a comment below, and if beanManager is null, WeldInitialListener obrains the beanManager from BeanManagerProxy.
// servlet containers may not be able to inject fields in a servlet listener

Can WeldTerminalListener get the beanManager by the same way as WeldInitialListener?
