Review request for 8016531: jconsole-plugin script demo does not work with nashorn

[Marcelo Rodrigues Costa]

Hi guys,

Just checking, on this section here:

// print a stack every 1 second for 5 seconds
load(src + "jstack.js");
..

Is that a readable javascript stack trace or is it the same result we get
from jstack? I will try to run this to see what I get..

Cheers!,
