Daniel Lord commented on ZOOKEEPER-1091:
----------------------------------------
Ooof been a long day. The fact that there are multiple znodes in the chroot is
inconsequential. The StringIndexOutOfBounds exception went away because my
chroot string got shorter than the full path returned in the event.
In any case I believe the rest of my test is valid. If there is a single
instance that has multiple zookeeper clients connected to the same ensemble if
they are completely disconnected then the paths in events can be messed up.
