When something is amiss with a production application, it can be very
productive to quickly look at the list of threads in an application 
and what state they are in. For your Ruby application running on 
JRuby, we can use JStack.

This article shows a quick example of a stuck Ruby application running
on JRuby and how to find out what is stuck and how to look at the 
elongated (read: ugly) stack trace and figure out how it maps to our 
Ruby source code.

Java and JStack

First let’s look at using JStack for a basic Java app, then look at 
the same app written in Ruby and running on JRuby.
