      Hi,

       

      Wildfly is emitting some warning logs when a application (using SFSB) is removed or when Wildfly is stopped :

      It seems thats is to be related to StatefulSessionObjectReferenceImpl.isRemoved npe due to ejbComponent.getCache() returning null · GitHub. The npe come from the ejbComponent.getCache() method which returning null.

      The problem never occurred in Wilfdly 8.x but exists in 9. and 10.x.

      Does anyone has already met this problem?

      Does anyone think it is important (these are "only" warning logs)?

       

      Thanks in advance for replying,

      Regards,
