AnsiFont[][] fonts = new AnsiFont[30][30];
// NoSuchMapperException
LoganSquare.serialize(fonts);
// NoSuchMapperException
LoganSquare.serialize(fonts[0]);
// Success
LoganSquare.serialize(fonts[0][0]);
```
Any ideas?

Start at the LoganSquare.serialize overloads shown in the report and trace how AnsiFont, AnsiFont[], and AnsiFont[][] are handled. Reproduce the NoSuchMapperException with the supplied examples; done means the reported array forms serialize successfully while the existing single-object case continues to work.
