The following code works fine with a single thread:
* def validateAricle = 'file:features/Articles.feature@validateArticle'
* def articles = {"id": 12}
* call read(validateArticle) articles
but having more than one thread I get the following error
Multi threaded access requested by thread Thread[pool-5-thread-1,5,main] but is not allowed for language(s) js.
This error can be reproduced from version 1.0.1 (it also happens to me in version 1.0.0). Before updating to version 1.0.0 I had no problems reusing features
