should derby use addShutdownHook() out of box?

[martin stanik <ma...@ecs-online.sk>]

hi,

I (silly boy) do not understand why derby engine needs to be shut down using
DriverManager.getConnection("jdbc:derby:;shutdown=true");

My application uses datasource, which is  _sometimes_  configured to use 
derby.
I do not like always execute the statement, as derby might be not in use and 
it could
cause loading derby classes.
I do not like idea to investigate my datasource if it does use derby or not.

Since 1.3 we have Runtime.addShutdownHook() - for me it looks like perfect 
solution
and derby should use it  by default after starting engine.

Am i wrong? Where i could found arguments?


thanks, martin
