Please do not use console if the user provides the password on the command line with -P.
The password is just read with the System.Console() when it is not specified after the -P argument.
That's not the problem. The problem is that you use System.console() when you should be using System.in in cases when the user specifies -P.
Try redirecting input from stdin to the BaseXClient - you'll see that it does not work. (It's a well-known limitation of java.io.Console). It leads to an infinite loop where BaseXClient ignores EOF. Really annoying.
Here for illustration what the problem is:
> java -cp ../WEB-INF/lib/basex-6.2.3.jar org.basex.BaseXClient -p 1985 -U admin -P admin
BaseX 6.2.3 [Client]
Try "help" to get some information.

Enjoy life.
Now when I put the commands in a file:
> cat testscript
create db test
xquery insert node <root /> into doc("test")
xquery doc("test")/root
exit
and then redirect stdin, it breaks:
> java -cp ../WEB-INF/lib/basex-6.2.3.jar org.basex.BaseXClient -p 1985 -U admin -P admin < testscript
BaseX 6.2.3 [Client]
Try "help" to get some information.

(and so on, I have to kill the program)
The reason is, as I said, that you're using java.io.Console when you should be using System.in
