Camel-Zookeeper does not read value store in zNode repeatedly

Issue

• I'm trying to use the camel-zookeeper component to read value store in zNode repeatedly but when I read it, I always get a null body. Below is the camel route.

<route>
 <from uri="timer://foo?fixedRate=true&amp;period=60000"/>
 <from uri="zookeeper://{{sys:zookeeper.url}}/test/simpleapp"/>
 <to uri="log:foundZoo?showAll=true" />
</route>
