> Running Hbm2Doc on a bunch of JPA annotated Entities, I get and IllegalArgumentException: To cannot be null in DocFileManager.getRef (see stack trace below). 
> Some HTML files (\hbm2doc\tables\default\MY_TABLE.html) gets created before Hbm2Doc ends with this exception. There might be something in one entity code making the table.ftl FreeMarker template fail. Improving error log could help (which table has a problem?).
