Thank you for posting this. Does the fact that our scoped objects are thread safe and that our scripts contain only function definitions without global variables makes any difference? Should I better create a separate scope on each invocation, possibly based on a scope prototype instance?
Unfortunately we are using Weblogic's version, we can't apply your patch.

It looks from here like this wasn't ever changed. http://mxr.mozilla.org/mozilla/source/js/rhino/src/org/mozilla/javascrip t/ClassCache.java Since raising the issue, we went through many rounds of load testing, reproducing the problem many times. We patched this by changing the HashMap class level variables to be ConcurrentHashMap. After many rounds of load testing we have never been able to reproduce the problem with the patch applied. Did that change ever get made? What should I do to help the process of getting that change into source?

Multiple scripts can be executed under one scope simultaneously as well. All presuming, as you stated, that the objects are immutable or you have made them thread safe yourself (Rhino does not make any effort to make the access to your objects thread safe, that will be your job).
