Maybe we could make it a platform issue so that we can query system tables instead of 
app tables. I don't like to *have* to install that table as I don't use any sequences.

I think we should also provide a default validationQuery. I suggest to 
use a simple "SELECT COUNT(*) FROM OJB_SEQ", as the ojb sequencemanager 
table will be used in about 95% of all OJB scenarios.

This an urgently needed feature!
