[jira] [Commented] (CURATOR-168) Error 'Path must start with /
character' caused by code 'setNode(event.getName());' in line 487 of
LeaderLatch.class source file in which 'event.getName()' sometimes only
return the last part of znode path instead of the full path.

-----------------------------------
Is this the same issue as CURATOR-165?

> We use LeaderLatch for leader election within our several zookeeper clients,but sometimes our leaderLatch stopped to work due to a error "Background exception was not retry-able or retry gave up java.lang.IllegalArgumentException: Path must start with / characte".
> To found the reason we tracked the execution of program in class LeaderLatch with debug mode,we found the code "setNode(event.getName());" in line 487 of LeaderLatch.class in which "event.getName()" code sometimes didn't return the full path of the znode but only return the last part of the full path,like "_c_b1097329-4a77-493b-806c-5c888067eeab-latch-0000004068", but the full path should be "/api1/leaders/_c_b1097329-4a77-493b-806c-5c888067eeab-latch-0000004068".
> So the when event.getName()=="_c_b1097329-4a77-493b-806c-5c888067eeab-latch-0000004068", the program will fail to go through the codes below:
> 1.LeaderLatch.checkLeadership() line 526
> 2.ZKPaths.getNodeFromPath() line 61
> 3.PathUtils.validatePath(path) line 46
> And then the LeaderLatch stopped to work.
