Java error stacktrace accumulation

I develop smpp client, when i receive InvalidResponseException time after time, my stacktrace increase:

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 org.jsmpp.session.SMPPSessionContext.close(SMPPSessionContext.java:10)
    at org.jsmpp.session.AbstractSession.close(AbstractSession.java:141)

then stacktrace was increase:

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.SMPPSessionContext.close(SMPPSessionContext.java:10)
    at org.jsmpp.session.AbstractSession.close(AbstractSession.java:141)
    at org.jsmpp.session.SMPPSession$EnquireLinkSender.run(SMPPSession.java:394)

and larger and larger. How it can be? Why stacktrace accumulate ? Between the response I set SMPPSessionContext variable to null, and SMPPSession to null

As far as I can see, there is a listener to the close session event that tries to open a new session. At the same time, the connectAndBind method, when detecting failure, tries to close the session, triggering yet another recursive cycle. So stop doing that, stop trying to open a session inside the close event callback (that's your class Gateway$SessionStateListenerImpl).
