Galder Zamarreño commented on ISPN-3218:
----------------------------------------
Hmmmm, weird. That NPE comes from converter being null. determineTypeConverter() does not return null unless one of the cached converters is null, which might be if the TypeConverter instances were not loaded correctly by the service loader in the constructor. I'm gonna try to run that branch to see if I can find out more...

> 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());
> }
> {code}
