-------------------------------------------

             Summary: JDBC_PING java.sql.SQLException: ORA-00001: unique constraint violated
                 Key: JGRP-1440
                 URL: https://issues.jboss.org/browse/JGRP-1440
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 2.12.1
         Environment: windows xp, oracle 11G
            Reporter: freeliuade freeliuade
            Assignee: Bela Ban
            Priority: Blocker

using JDBC_PING, create a very simple JChannel, unique constraint violated exception will throw sometimes.

it's a occationally issue. to easy reproduce it, using debug to let threads hold on JDBC_PING.writeToFile(...). line insert(...) (JDBC_PING line 246 in JGroups2.12.1.Final) you can find three threads will be hold on here. then using debug to step over this line, the unique constraint violated exception will throw.

I updated a debug diagram in here http://ww2.sinaimg.cn/mw600/649a9869jw1dr8m399uqdj.jpg
