Description

According to the JDK17 doc, ThreadGroup.destroy() is deprecated because

Deprecated, for removal: This API element is subject to removal in a future version.

The API and mechanism for destroying a ThreadGroup is inherently flawed. The ability to explicitly or automatically destroy a thread group will be removed in a future release.

We don't necessarily need to remove this usage now, but the warning sounds bad enough.
