Long term working Java console app not working now

I have a long term customer of a brainstorming software product that has a Java base and has been

used professionally for over ten years as a Java console application. He just upgraded to

macOS Sierra 10.12.2 and he says he is getting an error message that says, "You can't open the application

because it is not supported by this type of Mac."


Here are the Details:

Mac:

macOS Sierra 10.12.2

MBP 13 inch, mid 2012

Hardware Overview:

Model Name: MacBook Pro

Model Identifier: MacBookPro9,2

Processor Name: Intel Core i5

Processor Speed: 2.5 GHz

Number of Processors: 1

Total Number of Cores: 2

L2 Cache (per Core): 256 KB

L3 Cache: 3 MB

Memory: 8 GB

Boot ROM Version: MBP91.00D3.B0E

SMC Version (system): 2.2f44

Serial Number (system): C2VHQ0C6DTY3

Hardware UUID: 01719CDD-F21E-5E61-899A-8411A62F4B59

Sudden Motion Sensor:

State: Enabled


Here is some additional information about this type of app:

You can run Java from Terminal with a command something like this

example command line:

java myjar.jar MyApp

In our case, you go to the "terminal" program and then type in (or paste in):

java -cp JParaMindAndDict.jar JParaMind

in the directory where you installed ParaMind.


If you know about scripts, here is a shell script. The script is executable in the console.

#!/bin/sh

cd /Volumes/Macintosh\ HD/Applications/ParaMind\ for\ Java\ 1.0/

java -cp JParaMindAndDict.jar JParaMind

I am looking for any kind of help that one can give. Many people like this brainstorming

program and it's been a labor of love keeping the product going for 25 years now.


Thanks,

Robert
