We see this exception:
java.lang.ClassCastException: com.openhtmltopdf.render.AnonymousBlockBox cannot be cast to com.openhtmltopdf.newtable.TableCellBox
With HTML
<table> <tr> <td style="float:left">something</td> <td>xx</td> </tr> </table>
Granted float:left on a td doesn't make sense but a warning to the log is preferable to an exception if possible.
