Entry passivation doesn't work according to eviction strategy

       GlobalConfiguration globalConf = new GlobalConfigurationBuilder().nonClusteredDefault().build();
        ConfigurationBuilder builder = new ConfigurationBuilder();
        builder.clustering().cacheMode(CacheMode.LOCAL)
            .loaders().passivation(true).preload(false).shared(false)
            .addLoader(JdbcStringBasedCacheStoreConfigurationBuilder.class).fetchPersistentState(false).purgeOnStartup(false)
            .table()
                .databaseType(DatabaseType.MYSQL)
                .dropOnExit(false)
                .createOnStart(true)
                .tableNamePrefix("ISPN6Alpha2_STRING")
                .idColumnName("ID").idColumnType("VARCHAR(255)")
                .dataColumnName("DATA").dataColumnType("VARBINARY(1000)")

                .username("username")
                .password("password")
                .driverClass("com.mysql.jdbc.Driver")
            .eviction().strategy(EvictionStrategy.LRU).maxEntries(2);

        Configuration localConf = builder.build();
        DefaultCacheManager defCacheManager = new DefaultCacheManager(globalConf, localConf, true);
		  Cache<String, String> cache = defCacheManager.getCache();
		  cache.put("k1", "v1");
        cache.put("k2", "v2");
        //not yet in store (eviction.max-entries=2, LRU)
		  cache.put("k3", "v3");
        assertEquals("v3", cache.get("k3"));
        //now k1 evicted and stored in store
        assertEquals(2, cache.size()); <<< only 2 entries should remain in cache, k1 should be passivated and removed. But doesn't work!
