The following test fails if the new file cache store is configured with maxEntries property:
{code:java}
@Test
    public void testMaxEntriesAndLocationParametersDuringRestart() throws Exception {
        controller.start(CONTAINER);
        RemoteCacheManager rcm = new RemoteCacheManager(new ConfigurationBuilder().addServer()
                                                              .host(server.getHotrodEndpoint().getInetAddress().getHostName())
                                                              .port(server.getHotrodEndpoint().getPort())
                                                              .build());
        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"));
        //assert the existence of a single file in the filesystem
        File f = new File(singleFCSPath, "default.dat");
        assertTrue(f.exists());
        //assert that SingleFileCacheStore was registered
        MBeanServerConnectionProvider provider = new MBeanServerConnectionProvider(server.getHotrodEndpoint().getInetAddress().getHostName(), MANAGEMENT_PORT);
        assertEquals("[org.infinispan.persistence.file.SingleFileStore]", getAttribute(provider, CACHE_LOADER_MBEAN, "stores"));
        controller.kill(CONTAINER);
        controller.start(CONTAINER);
        assertEquals("v2", rc.get("k2"));
        assertEquals("v3", rc.get("k3"));
        assertNull(rc.get("k1")); //maxEntries was 2, this entry should be lost as the oldest entries are removed
//^^^^fails here, the entry is still there
        controller.stop(CONTAINER);
    }
{code}

Cache configuration:
