The OP in the original post used a string of "1.0" and wanted to
convert it into a boolean. If you use setBoolean in a prepared
statement it expects the argument to be a "numeric" type, so it is not
surprising that the string was converted to a double. You'd expect
something along the lines of ps.setBoolean(5,"xyz") to throw an error.

I don't know how many string values are to be considered "true" in the
application. Maybe use some regular expressions to suss out "true"
values?

My two cents.
