             Summary: Infinispan occasionally fails to locate an entry in a cache store when using a bounded data container
                 Key: ISPN-8959
                 URL: https://issues.jboss.org/browse/ISPN-8959
             Project: Infinispan
          Issue Type: Bug
          Components: Core, Eviction
    Affects Versions: 9.2.0.Final
            Reporter: Paul Ferraro
            Assignee: Paul Ferraro
            Priority: Blocker


If a Cache.get(...) needs to load an entry from the cache store, it uses the PersistenceUtil.loadAndStoreInDataContainer(...) method.

The method utilizes a DataContainer.compute(...) operation.  However, when the data container is backed by a caffeine BoundedLocalCache, the key of the ComputeAction will not be the same as the key from the command, since caffeine uses weak references for keys which use the hashCode returned by System.identityHashCode(...).  Since loadAndStoreInDataContainer(...) method calls the loadAndCheckExpiration(...) method using the key from the ComputeAction instead of the key from the command, it will fail to locate the entry in the cache store.
