Server mode fials on Mac OS

My program has run for over a year on Windows 7 and 10. Now the client wants to switch to Apples. 
This is the food pantry I mentioned a year ago, my charity project. I have a hsqldb database, version 
2.3.3,  that runs in server mode. The computer is running the latest OS and Java 8u111. I try to start 
the database with this command.

java –cp dist/lib/hsqldb.jar org.hsqldb.server.Server –database.0 file:DBData/MDFP –dbname.0 Meals

This is identical to the command on Windows and the directory structure is correct and the same on both
computers. I get the following response.

[1] 3736

[Server@5305068a]: 2016-11-30 20:18:51.925 SHUTDOWN : System.exit() is called next

With that, the database is not running. I have a related database for the same client that runs embedded
and all seems to be fine with it. The programs were developed under Netbeans on a Windows computer 
and transferred to the Mac. I also have recompiled under Netbeans on the Mac and get the same result.
I am not a Mac guru and don’t have any idea what could be wrong here. 

Any advice or help will be greatly appreciated.
