Look at the attached file hibernate.cfg.xml - if <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/mysql</property>
Hibernate Configuration view -> ... -> Database display correctly mysql database - but if
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306</property>
look like this
Hibernate Configuration view -> ... -> Database display nothing and the user can't understand what is wrong - I provide 2 screenshots
the same if
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/mysql1</property>
mysql1 - there is no such DB
as I think in first case Hibernate Configuration should display all mysql DBs and in the second case the user should get message -
something like "Can't find shuch DB"

Other thing - then I press right mouse button on Hibernate Configuration view -> ... -> Database - I expect to get possibility to configure
DB URL and may be some other properties - the best thing here if I'll get some dialog - or at least possibility to open hibernate.cfg.xml for edit.
For this I'll create other new issue...
