> ISPN version: f6d1761 - Galder Zamarreño, ISPN-3062 Push JCache TCK output to screen
> Using <compatibility enabled="true"> , storing an antry via HotRod, and reading it again via HotRod fails -> null is returned.
> If the compatibility mode is disabled, the HotRod's get() operation returns the correct value.
> The following code snippet illustrates the bug:
> {code:java}
> @Test
>    public void testHotRodPutRestGetTest() throws Exception {
>       final String key = "1";
>       // 1. Put with Hot Rod
>       RemoteCache<String, byte[]> remote = getHotRodCache();
>       assertEquals(null, remote.withFlags(Flag.FORCE_RETURN_VALUE).put(key, "v1".getBytes()));
>       assertArrayEquals("v1".getBytes(), remote.get(key));
> //^^^^ --------- fails here
>       // 2. Get with REST
>       HttpMethod get = new GetMethod(getRestUrl() + "/" + key);
>       getRestClient().executeMethod(get);
>       assertEquals(HttpServletResponse.SC_OK, get.getStatusCode());
>       assertEquals("v1".getBytes(), get.getResponseBody());
>    }
> {code}
> The tests along with the example configuration file can be found at https://github.com/mgencur/infinispan-server/tree/ISPN-3176/compatibility_tests
