Unrecognized option: -openjpa.Multithreaded=true

Hi there,

I may have noticed a problem in the current 
james-server-spring-app-3.8.1-app.zip  --> 
james-server-spring-app-3.8.1/bin/james-cli.sh .
When i try to execute ./james-cli.sh inside the bin-folder, this Error 
appears:

Unrecognized option: -openjpa.Multithreaded=true
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

I looked into the james-cli.sh and found the option in line 120. I think 
"-openjpa.Multithreaded=true" is missing a D --> 
"-Dopenjpa.Multithreaded=true".

I changed it and tested ./james-cli.sh again. Now I got a 
ClassNotFoundException. After this, I compared the james-cli.sh in 
v3.8.0 and v3.8.1 and noticed, v3.8.0 don't have the option 
"-openjpa.Multithreaded=true" included. So i decided to remove this 
option in my 3.8.1 james-cli.sh and tried again, now my james-cli.sh is 
working.

Is there an important reason for "openjpa.Multithreaded=true" or can we 
do without it?

Best Regards,
Dominik Katzenmaier
