> On the client side, JDK adds Class-Path elements from the job jar manifest
> on the classpath. In theory there could be many bundled jars in many directories such that adding them manually via libjars or similar means to task classpaths is cumbersome. If this property is enabled, the same jars are added
> to the task classpaths automatically.
