--------------------------------------
Summary: TreeCache throws IllegalArgumentException when node is a
substring of the requested path
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
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

(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}
