Question

也许我的怀疑有点傻。但我找不到与我的问题类似的答案。但经过一段时间的请求（大约20次调用此方法）后，客户端获得了java.lang.OutOfMemoryError：Java堆空间

客户是：

final ClientResource cr = new ClientResource(host + userInteracId);
try {
    Client httpClient = new Client(Protocol.HTTP);
    httpClient.setConnectTimeout(36000);
    cr.setNext(httpClient);
    JSONObject obj = new JSONObject();
    JsonRepresentation jr = new JsonRepresentation(obj);
    cr.put(jr);
    jr.release();

    cr.setNext(httpClient);
    Representation r = cr.get();
    result = new JsonRepresentation(r).getJsonObject();
    r.release();
} catch (Exception e) {
    result = new JSONObject();
} finally {
    cr.release();
    cr.getResponseEntity().release();
}

和例外是：

Answer 1

如果在jr.release（）或r.release（）之前引发异常，那么这些方法将永远不会被调用。 finally块中调用的唯一release（）是cr，而不是jr或r。

我建议在catch块中添加一些日志，以查看是否抛出异常。
