----------------------------------
[~fpj] That works boss.
[~michim] This is what fails:

Command failed: java.lang.IllegalArgumentException: Path must start with /
character
This is a zk with the patch that I attached here applied.
A clean 3.4.6 gives no indication that it worked (in fact I'm pretty sure it
does not work given that is what this issue is about -- that command-line args
are just by-passed):

> Key: ZOOKEEPER-1897
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1897
> Project: ZooKeeper
> Issue Type: Bug
> Components: java client, scripts
> Affects Versions: 3.4.6
> Reporter: Cameron Gandevia
> Assignee: Edward Ribeiro
> Fix For: 3.4.7, 3.5.0
>
> Attachments: ZOOKEEPER-1897.txt, ZOOKEEPER-1897v2.txt
>
>
> When running zookeeper 3.4.5 I was able to run commands using zkCli such as
> zkCli.sh -server 127.0.0.1:2182 ls /
> zkCli.sh -server 127.0.0.1:2182 get /blah
> After upgrading to 3.4.6 these commands no longer work.
> I think issue https://issues.apache.org/jira/browse/ZOOKEEPER-1535 was the
> reason the commands were running in previous versions.
> It looks like the client exits when a command is present.
> {code:title=ZooKeeperMain.java}
> void run() throws KeeperException, IOException, InterruptedException {
> if (cl.getCommand() == null) {
> System.out.println("Welcome to ZooKeeper!");
> boolean jlinemissing = false;
> // only use jline if it's in the classpath
> try {
> Class consoleC = Class.forName("jline.ConsoleReader");
> Class completorC =
> Class.forName("org.apache.zookeeper.JLineZNodeCompletor");
> System.out.println("JLine support is enabled");
> Object console =
> consoleC.getConstructor().newInstance();
> Object completor =
>
> completorC.getConstructor(ZooKeeper.class).newInstance(zk);
> Method addCompletor = consoleC.getMethod("addCompletor",
> Class.forName("jline.Completor"));
> addCompletor.invoke(console, completor);
> String line;
> Method readLine = consoleC.getMethod("readLine",
> String.class);
> while ((line = (String)readLine.invoke(console, getPrompt()))
> != null) {
> executeLine(line);
> }
