--------------------------------------

             Summary: Embedded JCache listener does not correctly return the previous value
                 Key: ISPN-8652
                 URL: https://issues.jboss.org/browse/ISPN-8652
             Project: Infinispan
          Issue Type: Bug
          Components: JCache
    Affects Versions: 9.1.4.Final, 9.2.0.Beta2
            Reporter: Galder Zamarreño


See discussion [here|https://github.com/infinispan/infinispan/pull/5624#discussion_r159410080].

The cache entry modified embedded event does not easily expose the previous value. To get the previous value, you need to listen for isPre=true event and cache the value. This is not user friendly.

The cache entry modified embedded event should probably expose a method to retrieve previous value regardless of whether isPre is true or false.

The JCache TCK currently only verifies that the previous value is non null, so we can just the current value and the TCK passes, but this is not correct.
