-----------------------------------
Summary: Compatibility mode does not work correctly in ISPN server
Key: ISPN-3182
URL: https://issues.jboss.org/browse/ISPN-3182
Project: Infinispan
Issue Type: Bug
Components: Server
Reporter: Martin Gencur
Assignee: Tristan Tarrant
Fix For: 5.3.0.Final
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}
