    Description

      Every execution of a JS script on Java 11 runtime logs a Nashorn deprecation warning:

      "Warning: Nashorn engine is planned to be removed from a future JDK release"

      There is a flag to turn it off but that has to be passed as a flag during ScriptEngine construction, its not something users can turn off from "the outside" (i.e. not a Java flag)

      See https://stackoverflow.com/questions/55641738/how-to-hide-java-11-nashorn-deprecation-warnings

      Note Java 11 is one of the off the shelf docker bundles Camunda provides.

      This excessive logging consumes resources, slows the engine down, adds log noise, leaves a negative impression and causes alarm.
