Sami Nurminen commented on CAMEL-8529:
--------------------------------------
There seems to be camel context property REUSE_SCRIPT_ENGINE used in
org.apache.camel.builder.script.ScriptBuilder which seems to be undocumented?
Maybe it could be exposed somehow, for example same way as "cacheScript" option
in the language component eg. reuseScriptEngine true/false. At least in my
machine javascript didn't have any concurrence issues with simple test copied
from RubyScriptTextTest.

> Key: CAMEL-8529
> URL: https://issues.apache.org/jira/browse/CAMEL-8529
> Project: Camel
> Issue Type: Improvement
> Components: camel-script
> Affects Versions: 2.15.0
> Reporter: gui
> Assignee: Willem Jiang
> Attachments: scriptbuilder.patch
>
>
> When a script is compiled (eg in case of js), the scriptbuilder is (re)
> creating a new engine instance on every invocation, although the compiled
> script has already an engine attached.
> This cause a lot of unnecessary engine initialization on every invocation.
