-----------------------------------------

I haven't checked the other classes but I suppose they might have similar issues too.

> {{MetaImpl.MetaColumn}} which is used as a record for {{DatabaseMetadata#getColumns}} doesn't follow JDBC spec:
> several fields have incorrect types:
> - bufferLength should be an int (based on name, but not clarified in spec)
> - sqlDataType should be an int
> - sqlDatetimeSub should be an int
> - sourceDataType should be a short
> some fields also have incorrect nullability:
> - columnSize, charOctetLength and numPrecRadix can be null when they don't apply to their specific types
> - isNullable, isAutoincrement and isGeneratedcolumn should be a nullable fields (although they are not primitive fields), with value set to the empty string if undefined.
