Java org.json.JSONException:JSONObject文本在启动时必须在字符2处以“{”开头

我正在使用RHEL 6.5，java 1.7.0_45。请帮帮我

Guice无法创建org.apache.shindig.social.sample.spi.JsonDbOpensocialService的新实例。请查看原始异常-org.json.JSONException:JSONObject文本必须以'{'在字符2tanks Joakim处获取您的评论。但是相同的shindig-server-1.1-SNAPSHOT.war在RHEL4中使用相同的Jetty 6.1成功部署在另一个设置上。我在哪里检查JSON相关的内容？请帮助查看JsonDbOpensocialService的构造函数，第128行，正如我从shindig的源代码中看到的，可能有点不同的版本空或不是JSON st环由数据库返回。所以错误不在jetty本身。
