我正在使用google-api-client-java
1.2.1-alpha执行POST请求，并在我执行execute（）HttpRequest时得到以下stacktrace。

在我捕获并忽略从先前的POST到相同URL的403错误并重新用于后续请求的传输之后，它立即发生。（这是将多个条目插入同一ATOM提要的循环）。

403之后，我应该做些什么来“清理”吗？

Exception in thread "main" java.lang.IllegalStateException: Invalid use of SingleClientConnManager: connection still allocated.
Make sure to release the connection before allocating another one.

为什么我下面的代码试图获取 新的 连接？
