code: public static ImmutableList<Commented<ExpressionTree>> findCommentsForArguments(
        MethodInvocationTree methodInvocationTree, VisitorState state) {
      int startPosition = state.getEndPosition(methodInvocationTree.getMethodSelect());

docs: Attach comments to nodes on arguments of method calls. Calls such as {@code test(param1 /* c1
  *&#47;, /* c2 *&#47; param2)} will attach the comment c1 to {@code param1} and the comment c2
  to {@code param2}.
  
  <p>Warning: this is expensive to compute as it involves re-tokenizing the source for this node
  
  <p>Currently this method will only tokenize the source code of the method call itself. However,
  the source positions in the returned {@code Comment} objects are adjusted so that they are
  relative to the whole file.
