Redundant @SuppressWarnings("deprecation") for Thread.getThreadGroup()

[Andrey Turbanov]

Hello.
IntelliJ IDEA highlights redundant warning suppressions for
Thread.getThreadGroup() calls in ThreadGroup calls.
All of them were added during Loom integration.

https://github.com/openjdk/jdk/blob/79ccc791f275be7cfea95ff0ce8cf7361c7f08ad/src/java.base/share/classes/java/lang/ThreadGroup.java#L378

Is it still planned to deprecate this method? Or can I remove
redundant suppressions?
