For instance, it will share the same classloader that the task is loaded from.
This is the fastest level of isolation.

This states that the work should be run in a thread with an isolated classloader.  +

This will become an error in Gradle 6.0.

==== Method `WorkerExecutor.submit()` is deprecated

The `WorkerExecutor.submit()` method is now deprecated.
The new `noIsolation()`, `classLoaderIsolation()` and `processIsolation()` methods should now be used to submit work.
See <<worker_api.adoc#tasks_parallel_worker,the section on the Worker API>> for more information on using these methods.
