I have several columns that are char(1) in sybase. If I set then to a space the try to fetch I get:

Apparently the jtds driver interprets the single space as an empty string because sybase respresents empty strings as single spaces. Hibernate assumes there is a character at [0] and tries to address it to construct a Character and it blows.

Any fix for this?
