Review comment:
Actually, it should work as expected. Java determines how to treat incoming
arguments at the compilation stage, so if the reference has a non-array type,
it will be treated as a single element of vararg even if actual type of the
object is an array.
Here is these two different cases:
```
addRow(new String[]{"a", "a"});
```
and the same case as in the code:
```
Object value = new String[]{"a", "a"};
addRow(value);
```
