そのため、Guava v18 を使用しています。この内容で多くのスレッドが進行中です:

グアバの構成は次のとおりです。

  @SuppressWarnings("unchecked")
  @Override
  protected <K, R> CacheWrapper<K, R> newCacheConfiguration(Fetcher fetcher, String cacheName, int maxElementsInMemory,
      int timeToIdleSeconds, int timeToLiveSeconds)
  {
    Cache existingCache = manager.getCache(cacheName);
    CacheWrapper<K, R> cache;
    if(null == existingCache) 
    {
      cache = new GuavaCacheWrapper<>(CacheBuilder.newBuilder()
        .maximumSize(maxElementsInMemory)
        .expireAfterAccess(timeToIdleSeconds, SECONDS)
        .refreshAfterWrite(timeToLiveSeconds, SECONDS)
        .recordStats()
        .build( CacheLoader.asyncReloading(fetcher.getAs(CacheLoader.class), executors)));
      manager.addCache(cacheName, cache);
    }
    else 
    {
      cache = (CacheWrapper<K, R>) ((GuavaCache) existingCache).getNativaGuavaCache();
    }
    return cache;
  }

何が問題を引き起こしているのかを確認するために何をチェックできるかについて、私は少し無知です。私が確認できることを提案してもらえますか？
