Java错误堆栈跟踪累积

Question

我开发了smpp客户端，当我一次又一次地收到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)

然后增加堆栈跟踪：

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)

越来越大越来越大。怎么会这样呢？为什么堆栈跟踪会累积？在响应中，我将SMPPSessionContext变量设置为null，并将SMPPSession设置为null

Answer 1

据我所知，有一个close session事件的侦听器试图打开一个新会话。同时，当检测到故障时，connectAndBind方法会尝试关闭会话，从而触发另一个递归周期。因此，停止这样做，停止尝试在close事件回调(即您的类Gateway$SessionStateListenerImpl)中打开会话。
