Depends on how much of derby specific code you want to put in ij, Jorgen. 

I must admit I was surprised at seeing the derby system shutdown being attempted
when we do a quit itself.

My impression about ij was ij is a general jdbc front end tool. It can be used 
with any database
that supports a jdbc driver. This shutdown attempt with use to any other 
database (different
jdbc url) will surely fail. Well maybe that is why we ignore the SQLExceptions 
upon doing
this.

Adding more and more derby specific code to ij, makes ij more and more a
derby specific tool and lesser and lesser a general jdbc interface supporting 
front-end.

For now I will lower the severity of the issue. I think we can take it from 
there.

I will also leave the issue open.
