用JVM thread dump诊断quartz的问题

现场报与其他系统的数据同步停止了。系统中间件是weblogic，用定时框架quartz调用webservices，同步的信息记录在一张表中。先获取weblogic日志，并未发现有同步的错误信息。现场发布了十几个weblogic节点，定时任务放在一个节点上。

这个定时任务是挂了还是hang住了，这个时候得看thread dump：

发现代码停在at com.gg.soa.tbi.client.common.util.SoaClientUtils.getPort(SoaClientUtils.java:51)，这一行代码是webservices在做连接服务器。检查了一下代码，没有加超时设置。
