[ https://issues.apache.org/jira/browse/ZOOKEEPER-1091?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13113092#comment-13113092 ]
Matthias Spycher commented on ZOOKEEPER-1091:
---------------------------------------------
Thomas is right. One of the unit tests in the patch to ZOOKEEPER-961 verifies that the StringIndexOutOfBounds no longer occurs. Also, if any path from the server is too short for the current chroot, we no longer throw the exception. Instead a warning is issued and the raw path passed in the event.
