Question

我开发了smpp客户端，当我一次又一次收到InvalidResponseException时，我的堆栈跟踪增加了：

org.jsmpp.extra.NegativeResponseException: Negative response 0000000f found
    at org.jsmpp.session.AbstractSession.validateResponse(AbstractSession.java:162)
    at org.jsmpp.session.AbstractSession.executeSendCommand(AbstractSession.java:203)
    at org.jsmpp.session.SMPPSession.sendBind(SMPPSession.java:143)
    at org.jsmpp.session.SMPPSession.connectAndBind(SMPPSession.java:86)
    at com.sms.client.gw.Gateway.newSession(Gateway.java:107)
    at com.sms.client.gw.Gateway.getSession(Gateway.java:81)
    at com.sms.client.gw.Gateway.access$300(Gateway.java:33)
    at com.sms.client.gw.Gateway$SessionStateListenerImpl.onStateChange(Gateway.java:196)
    at org.jsmpp.session.AbstractSessionContext.fireStateChanged(AbstractSessionContext.java:69)
    at org.jsmpp.session.SMPPSessionContext.changeState(SMPPSessionContext.java:44)
    at org.jsmpp.session.AbstractSessionContext.close(AbstractSessionContext.java:58)
    at org.jsmpp.session.SMPPSessionContext.close(SMPPSessionContext.java:10)
    at org.jsmpp.session.AbstractSession.close(AbstractSession.java:141)

然后堆栈跟踪增加：

org.jsmpp.extra.NegativeResponseException: Negative response 0000000f found
    at org.jsmpp.session.AbstractSession.validateResponse(AbstractSession.java:162)
    at org.jsmpp.session.AbstractSession.executeSendCommand(AbstractSession.java:203)
    at org.jsmpp.session.SMPPSession.sendBind(SMPPSession.java:143)
    at org.jsmpp.session.SMPPSession.connectAndBind(SMPPSession.java:86)
    at com.sms.client.gw.Gateway.newSession(Gateway.java:107)
    at com.sms.client.gw.Gateway.getSession(Gateway.java:81)
    at com.sms.client.gw.Gateway.access$300(Gateway.java:33)
    at com.sms.client.gw.Gateway$SessionStateListenerImpl.onStateChange(Gateway.java:196)
    at org.jsmpp.session.AbstractSessionContext.fireStateChanged(AbstractSessionContext.java:69)
    at org.jsmpp.session.SMPPSessionContext.changeState(SMPPSessionContext.java:44)
    at org.jsmpp.session.AbstractSessionContext.close(AbstractSessionContext.java:58)
    at org.jsmpp.session.SMPPSessionContext.close(SMPPSessionContext.java:10)
    at org.jsmpp.session.AbstractSession.close(AbstractSession.java:141)
    at org.jsmpp.session.SMPPSession.connectAndBind(SMPPSession.java:100)
    at com.sms.client.gw.Gateway.newSession(Gateway.java:107)
    at com.sms.client.gw.Gateway.getSession(Gateway.java:81)
    at com.sms.client.gw.Gateway.access$300(Gateway.java:33)
    at com.sms.client.gw.Gateway$SessionStateListenerImpl.onStateChange(Gateway.java:196)
    at org.jsmpp.session.AbstractSessionContext.fireStateChanged(AbstractSessionContext.java:69)
    at org.jsmpp.session.SMPPSessionContext.changeState(SMPPSessionContext.java:44)
    at org.jsmpp.session.AbstractSessionContext.close(AbstractSessionContext.java:58)
    at org.jsmpp.session.SMPPSessionContext.close(SMPPSessionContext.java:10)
    at org.jsmpp.session.AbstractSession.close(AbstractSession.java:141)
    at org.jsmpp.session.SMPPSession$EnquireLinkSender.run(SMPPSession.java:394)

越来越大。它怎么样？为什么堆栈跟踪累积？在响应之间我将SMPPSessionContext变量设置为null，将SMPPSession设置为null

据我所见，有一个试图打开新会话的close session事件的监听器。同时，connectAndBind方法在检测到失败时尝试关闭会话，触发另一个递归循环。所以停止这样做，停止尝试在close事件回调中打开一个会话（这是你的班级Gateway$SessionStateListenerImpl）。

Java错误堆栈跟踪累积
