thank you for this precision.

I have made more tests and have some more remarks.

I replace the BUILTIN provider by a UserAuthenticator implementation class.
I found that the example included in the documentation is not working if a 
system shutdown is done.
In this case the authenticateUser method of the UserAuthenticator 
implementation is called with null prameters (except info which has the 
"shutdown" property set). The example return false if userName is null so 
system shutdown raise a "Connection authentication failure occurred." exception.

If we do a system shutdown, it doesn't seam necessary to make database shutdown 
first (right ?), but do we need to make a system shutdown if we have previously 
made a database shutdown ?

  Forgot to add that Yes, the documentation note should be fixed to mention 
that if authentication has been enabled, then you do need to authenticate in 
order to shutdown a Derby system.

  Thanks

    You have to set it _if_ you have defined Derby's BUILT-IN user 
authentication at the System level (e.g. setting username / password in 
derby.properties file) versus having defined users at the database level (e.g. 
database-level properties) - note that both types of users are NOT exclusive, 
meaning you can have users defined at the system and database levels.

    "Setting the property as a system-wide property creates system-wide users. 
Setting the property as a database-wide property creates users for a single 
database only."

    See database-level properties versus system-level ones:

      Hi,
      The documentation says : << Applications in an embedded environment shut 
down the Derby system by specifying the shutdown=true attribute in the 
connection URL. To shut down the system, you do not specify a database name, 
and **you must not specify any other attribute**.>>
      Even if authentication is enabled it doesn't seams that you have to set 
the user/password attributes, only database shutdown needs these attributes.
      In fact I HAVE TO set the user/password attributes to shutdown the system 
or I have a "Connection authentication failure occurred" exception.

      So my question is : is-it an error in the documentation or a bug or a 
misunderstanding ?

      Thanks,
