TypeConverterInterceptor throwing NPE in distributed compatibility mode ----------------------------------------------------------------------- Key: ISPN-3218 URL: https://issues.jboss.org/browse/ISPN-3218 Project: Infinispan Issue Type: Bug Components: Server Affects Versions: 5.3.0.CR1 Reporter: Martin Gencur Assignee: Tristan Tarrant Priority: Critical Fix For: 5.3.0.Final Attachments: standalone-compatibility-mode.xml The following test fails for the server in DIST mode when in compatibility mode. It does not happen in normal DIST mode: {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())); //^^^^this put operation fails assertArrayEquals("v1".getBytes(), remote.get(key)); // 2. Get with REST HttpMethod get = new GetMethod(getRestUrl() + "/" + key); getRestClient().executeMethod(get); assertEquals(HttpServletResponse.SC_OK, get.getStatusCode()); assertEquals("v1".getBytes(), get.getResponseBody());
