Following just regular installer instructions: Error: Could not find or load main class org.jruby.Main

Kierens-MBP:bin kieren$ ./logstash --?

My pwd doesn't contain any colon. I literally just downloaded and unzipped the latest logstash, installed the JDK as requested, and tried to run an example.

I'm following https://www.elastic.co/blog/getting-started-with-hosted-elasticsearch-v5-and-a-sample-dataset, which clearly a bit dodgy since the git repo it says to use the conf from indicated that's a legacy conf.

But I'm not getting that far. Why won't a clean install of logstash run at all, please?

Ok, some more digging, the install pages say Java 9 is not supported.

Why then does invoking Logstash and clicking "More info" take me to a page with a big fat Java 9 download button?

Update: Java 8 fails in the same way.

Update.. 'unzip logstash-whatever.zip' on the commandline didn't work, however if I extract the zip using OS X / Finder it's fine.

I say fine, I then get:

Any tips at all?

Is this - https://stackoverflow.com/questions/41391781/logstash-5-1-1-bad-uriis-not-uri - the answer?

Seriously, how frail is this thing? Why doesn't the install guide mention this, yet it mentions colons?
