Possible heap pollution from parameterized vararg type

Reports methods with variable arity, which can be annotated as @SafeVarargs. The @SafeVarargs annotation suppresses unchecked warnings about parameterized array creation at call sites.

Example:

public class Foo<T> {
  private List<T> list = new ArrayList<>();

  public final void safeVarargs(T... elements) {
    Collections.addAll(list, elements);
  }
}

After the quick-fix is applied:

public class Foo<T> {
  private List<T> list = new ArrayList<>();

  @SafeVarargs
  public final void safeVarargs(T... elements) {
    Collections.addAll(list, elements);
  }
}

This annotation is not supported under Java 1.6 or earlier JVMs.
