SUGGESTION

Simplification

Suppression

Suppress false positives by adding the suppression annotation @SuppressWarnings("JsonNodeOptionalInt") to the enclosing element.

Disable this rule by adding -XepOpt:Refaster:NamePattern=^(?!JacksonRules\$JsonNodeOptionalInt).* as compiler argument.

Samples

Shows the difference in example code before and after the Refaster rule is applied.

 ImmutableSet<Optional<JsonNode>> testJsonNodeOptionalInt() {
   return ImmutableSet.of(
-      NullNode.getInstance().get(1).asOptional(),
-      NullNode.getInstance().path(2).asOptional(),
-      Optional.of(NullNode.getInstance().get(3)),
-      Optional.ofNullable(NullNode.getInstance().get(4)));
