---------------------------------------
http://db.apache.org/derby/docs/dev/devguide/cdevbabejgjd.html
Add to Mandatory permissions
permission java.util.PropertyPermission "derby.storage.jvmInstanceId", "write"
This property is used by Derby to prevent accidental boot of the database by
two class loaders. Boot of the database by two class loaders can cause
corruption. This permission requirement is new to 10.3. Therefore if it is
not set, a message will print to the log that Derby cannot protect from dual
boot and possible corruption.
Add the following line to policy file examples:
permission java.util.PropertyPermission "derby.storage.jvmInstanceId", "write"

> Dual embedded boot of a database from different classloaders may cause
> corruption. In order to prevent this, Derby requires read/write access to
