Shiow the table DDL that causes this fault. What database are you using? Anything else that might help replicate/explain the error.

I had this error trying to reverse engineer a hsqldb database with boolean columns. If this could be related, then have a look at:

I am getting the same error. The problem is that the error message does not say which column is the problem, a more detailed error message in the exception would help.
