Use cases for shutdown=true in embedded Derby

[Антон Крылов]

Hello,

I was wondering when would one want to shut down an embedded Derby database
using shutdown=true in recent Derby versions? Liquibase does use this, and
this very part causes trouble both in Derby
(https://issues.apache.org/jira/browse/DERBY-2068 ) and Liquibase
(https://liquibase.jira.com/projects/CORE/issues/CORE-3144 )
