Hi  Stijn,

We *suspect* a bug fix ( https://bugs.openjdk.java.net/browse/JDK-8145550) that is in jdk9 may fix the one you describe as well. We'd want to backport to a jdk8u after due backport process. FYI.

Thanks,
-Sundar

At first glance it doesn’t seem to be thread related.  We’ll poke at it but it 
would be helpful if you reduced the problem.

Dear fellow developers,
First of all thank you for your work on Nashorn. I am pretty excited at the 
possibilities of being able to integrate my two favorite languages, Java and 
Javascript.
I have two concrete questions and a problem (which caused the questions):
1. Can a Nashorn engine be used across threads (using ScriptContext or Bindings 
for isolation)?2. Is there a good example of using Nashorn from a Servlet 
Filter?
My problem:
I am struggling with server-side rendering of React components using Nashorn. I 
am deploying to OpenShift and whenever I try to make my app listen to the rout 
route, I run into a weird ClassCastException somewhere inside the Nashorn code. 
I now think this is due to a heartbeat request OpenShift's haproxy is doing on 
my app that is causing (relatively) high load and triggering a concurrency 
problem... This leads me to believe I am doing something wrong in the way I 
create the script engine and using script contexts in a ThreadLocal to isolate 
the different threads.
I have formulated my question, including logs and relevant code, on 
StackOverflow.com.http://stackoverflow.com/questions/34276136/classcastexception-nativeregexpexecresult-cannot-be-cast-to-nativearray

Could one of you maybe have a look at my situation, specifically my servlet 
filter code and tell me if I am doing it wrong and if so, what I should 
change?(I tried instantiating a different engine per thread and saving them in 
a ThreadLocal, but this leads to OutOfMemory errors quickly)
Thank you for any tips, pointers to docs etc that you could spare.
With kind regards,
-Stijn
