Dear Derby users,
The next feature release of Derby will close some security holes:
1) When authentication is turned on, only the owner of a database will
be allowed to shut it down, encrypt it, and hard-upgrade it.
2) When you boot the network server as the VM's entry point, the server

Table and column names are called SQL identifiers and, according to the
