ImmutableMultisetBuilder

SUGGESTION

Simplification

Suppression

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

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

Samples

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

 ImmutableMultiset.Builder<String> testImmutableMultisetBuilder() {
-  return new ImmutableMultiset.Builder<>();
+  return ImmutableMultiset.builder();
