I believe that this belongs here (otherwise please let me know under what module this should be reported)

it would be nice to add a rule to the Java 8 -> Java 11 migration to apply the following transformation :

Set<String> s = Collections.unmodifiableSet(new HashSet<>(Arrays.asList("A", "B")));

After

Set<String> s = Set.of("A", "B")
