Hello! I’m Austin and I like Nashorn.
I, personally, have been using Nashorn to try and run NodeJS modules under it, particularly UglifyJS2.
All the files I mention following this are available in a Github release below of my app I’m hoping to use Nashorn with. There is a executable Jar file with the correct directories and instructions on how to run on the website below. The source code is available here below, also.
My app is currently a test that wraps UglifyJS2 with bindings in net.austin.chisel.wrappers.UglifyWrapper.java. You can ignore the LESS stuff because that runs on Rhino and isn’t my library (it’s here <https://github.com/marceloverdijk/lesscss-java>).
The important thing is that when I run UglifyJS2 natively under NodeJS (V8), then the compile time is around 1 second more or less (I had no way to time it, that I knew of), but when I run my wrapper, it takes around 47.5 seconds to do the same! However, the resulting copies are verbatim and Nashorn functioned entirely correct, just a big performance problem. @lagergren <https://twitter.com/lagergren/status/544231448900034561> said this might be a warm-up issue.
For clarity, I’m running what I believe to be the newest public release of the JDK/JRE. I’m on OS X Yosemite. When I run java -version I get this:
java version "1.8.0_25"
Java(TM) SE Runtime Environment (build 1.8.0_25-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)
