Labeled switch rule has redundant code block

Reports labeled rules of switch statements or switch expressions that have a redundant code block.


String s = switch (n) { case 1 -> { yield Integer.toString(n); } default -> "default"; };

After the quick-fix is applied:

String s = switch (n) { case 1 -> Integer.toString(n); default -> "default"; };

This inspection only reports if the language level of the project or module is 14 or higher.
