---------------------------------------------------
Hi [~andreina],
If JAVA_HOME isn't set, we default to whatever is available in $Path. See:
https://github.com/apache/zookeeper/commit/90ef80c0a2593207be5436acf0270c1e160f0c78
Maybe your patch should only error out if JAVA_HOME isn't set *and* there's no
java in the $PATH?
> If JAVA_HOME is not set zk startup and fetching status command execution
> result misleads user.
