玩！框架和ElasticSearch StackOverflowError

Question

我正在使用Play！ Framework版本2.1.5，QBox.io上的Jest 0.0.4和ElasticSearch 0.90.5。

我有下面的代碼位：

try { 
    SearchConfig config = new SearchConfig(); 
    JestClient client = config.jestClient(); 
    Logger.debug("client exists"); 
    Index index = new Index.Builder(post).index("ads").type("ad").build(); 
    Logger.debug("index exists"); 

    client.execute(index); 
    Logger.debug("post client.execute()"); 
} catch (IOException e) { 
    e.printStackTrace(); 
} catch (Exception e) { 
    e.printStackTrace(); 
} 

當我運行它使我有以下錯誤：

[debug] application - client exists 
[debug] application - index exists 
[debug] application - index: io.searchbox.core.Index@2ddf188f 
[error] application -

我是新來播放和ElasticSearch（和玩笑）我不知道如何解決這個SOError問題。任何幫助表示讚賞！提前致謝！

增加您的應用程序的堆棧大小沒有幫助嗎？

可以使用jvm選項-Xss4m來完成，其中4m比os上的默認值大。
