'Hazlecast eviction is not working with USED_HEAP_SIZE with Hazlecast 5.0

I'm having below map configuration for Hazlecast

private MapConfig initializeDefaultMapConfig(int ttlMinutes,int size) {
    MapConfig mapConfig = new MapConfig();
    EvictionConfig evictionConfig = new EvictionConfig();
    evictionConfig.setEvictionPolicy(EvictionPolicy.LRU);
    evictionConfig.setMaxSizePolicy(MaxSizePolicy.USED_HEAP_SIZE);
    evictionConfig.setSize(size);
    mapConfig.setBackupCount(0);
    mapConfig.setEvictionConfig(evictionConfig);
    mapConfig.setTimeToLiveSeconds(ttlMinutes);
    mapConfig.setMaxIdleSeconds(ttlMinutes);
    return mapConfig;   
}

I am running Hazlecast in single node instance only. It still exceeds the specified memory size. Please suggest.
