> TreeCache throws IllegalArgumentException when node is a substring of the

> Key: CURATOR-236
> URL: https://issues.apache.org/jira/browse/CURATOR-236
> Project: Apache Curator
> Issue Type: Bug
> Components: Recipes
> Affects Versions: 2.8.0
> Environment: JDK 1.7.0_71; OSX Yosemite;
> Reporter: Joe Littlejohn
> Assignee: Scott Blum
> Priority: Minor
>
> The javadocs for the new TreeCache state that {{getCurrentChildren}} will
> return {{null}} when the given path is not found in the cache. This seems to
> be the case for most paths, however if the given path contains an existing
> node as a substring, an exception is thrown:
> {code}
> Unhandled java.lang.IllegalArgumentException
> Path must start with / character
> PathUtils.java: 54

> {code}
> (please ignore the strangely formatted exception, I'm running a Clojure repl
> in Emacs)
> So, lets imagine that I have the following nodes in zookeeper:
> {code}
> /foo
> /foo/bar
> /foo/baz
> {code}
> If I have a TreeCache {{t}} pointing at {{/foo}} then I will get the
> following results:
> {code}
> t.getCurrentChildren("/sss") => nil
> t.getCurrentChildren("/foo/sss") => nil
> t.getCurrentChildren("/foo/barsss") => IllegalArgumentException: Path must
> start with / character
> {code}
