Redundant java.lang.SafeVarargs annotation. Varargs element type java.lang.String is reifiable.

[domdorn]

Hi!
I'm using immutables-value 2.7.5

I'm getting a compiler warning Redundant java.lang.SafeVarargs annotation. Varargs element type java.lang.String is reifiable. because immutables creates the @SafeVarargs annotation even for primitive types/reifiable types (like String)

my interface looks like this

@Value.Style(
  typeAbstract = "Abstract*",
  typeImmutable = "*",
  validationMethod = Value.Style.ValidationMethod.NONE,
  passAnnotations = {
      Nullable.class,
      NotNull.class,
      NotEmpty.class,
      Size.class,
      Max.class,
      Min.class,
      Pattern.class,
      Digits.class,
      JsonProperty.class
  },
  defaults = @Value.Immutable,
  visibility = Value.Style.ImplementationVisibility.PUBLIC)
@VavrEncodingEnabled
@Immutable
public interface AbstractLocalesDto {
....

  @NotNull
  List<String> available();
...
}

which then creates

.....
    @SafeVarargs
    public final Builder addAvailable(String... elements) {
      this.available_list = this.available_list.appendAll(Arrays.asList(elements));
      return this;
    }
...
}

in my understanding, the @SaveVarargs should only be generated when the variable argument types contain type parameters?

Why does this matter? I'm trying to harden my project by setting the -Werror javac compiler option, but this code in immutables is still preventing that.

Putting the @SuppressWarnings({ "all", "varargs" }) on my interface does work as a workaround, but feels wrong.
