I suppose it is fine, as long as none of the data is meant to be changed 
at run time. If any of these properties were set during a request based 
on some condition, the next request might get the conditionally set 
value from the previous request, rather than the expected default. I'm 
not familiar enough with CDBI to know whether this might occur, so I 
thought I would mention it. If that kind of thing just doesn't happen, 
then I guess there is nothing to worry about.

I only noticed it because I was storing a Logger type object in a class 
property (so that my entire class hierarchy could use a uniform logging 
interface), and I got strange behavior because the object persisted.
