> ...it is not possible to retrieve the cache entry from the cache store after server restart, as demonstrated by the following test:
> {code:java}
> RemoteCache<String, String> rc = rcm.getCache();
>         rc.clear();
>         assertNull(rc.get("k1"));
>         rc.put("k1", "v1");
>         rc.put("k2", "v2");
>         rc.put("k3", "v3");
>         assertEquals("v1", rc.get("k1"));
>         assertEquals("v2", rc.get("k2"));
>         assertEquals("v3", rc.get("k3"));
>         controller.kill(CONTAINER);
>         controller.start(CONTAINER);
>         assertEquals("v2", rc.get("k2"));
> //^^^fails here - unable to find k2
>         assertEquals("v3", rc.get("k3"));
>         assertNull(rc.get("k1")); //maxEntries was 2, this entry should be lost as the oldest entries are removed
>         controller.stop(CONTAINER);
> {code}
> Note that preload is set to false for this test. When I set it to true, the test passes.
> I tried to modify BaseCacheStoreFunctionalTest#testPreloadAndExpiry, disable "preload" and retrieve the cache entries after server restart by calling cache.get() (not from DataContainer) and the test passed (I ran SingleFileCacheStoreFunctionalTest which extends BaseCacheStoreFunctionalTest). So it seems the bug is related to the server distribution.
