java.lang.IllegalArgumentException: Illegal JID

1 问题描述
做微信在线客服时，连接openfire，跟踪源码，出现如下问题。而且发现起了很多线程。

Exception in thread "httpbind-worker-12" java.lang.IllegalArgumentException: Illegal JID: zx0001@[object HTMLInputElement]/Stropheat org.xmpp.packet.JID.<init>(JID.java:542)at org.xmpp.packet.Packet.<init>(Packet.java:94)at org.xmpp.packet.IQ.<init>(IQ.java:105)at org.jivesoftware.openfire.SessionPacketRouter.getIQ(SessionPacketRouter.java:86)at org.jivesoftware.openfire.SessionPacketRouter.route(SessionPacketRouter.java:67)at org.jivesoftware.openfire.http.HttpSession.sendPendingPackets(HttpSession.java:639)at org.jivesoftware.openfire.http.HttpSession$HttpPacketSender.run(HttpSession.java:1271)at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142)at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)at java.lang.Thread.run(Thread.java:745)

2 解决方案
出现多个线程的原因，是因为我前台js启动了一个定时器，几秒就发起iq请求，
The input is not a valid JID domain part: [object HTMLInputElement]
则表明self.connection.ping.ping(seat,_success, _error);中seat的值是错误的。
