After restarting services AND restarting the server, we are unable to add/remove/change user records. 
Per logs, it appears our database is starting in READ ONLY. 

Booting Derby version The Apache Software Foundation - Apache Derby - xx.x.x.x - (1405108): instance yyyyy 
on database directory DevTest_Home//database/lisa.db in READ ONLY mode....

All supported DevTest environments.

The user starting DevTest does not have permissions to modify the following file:
DevTest_Home/database/lisa.db/db.lck

Either:
1. Have someone with the correct permissions start DevTest.
2. Delete this file and start DevTest. A new file will be created.

Note: Derby is not a supported database for DevTest. Derby is used to confirm the DevTest install and debugging.
