You may override the Network Server's impulse to install a security
manager if, for some reason, you need to run your application outside
Java's security protections.
CAUTION:
You incur a severe security risk by opening
up the server to all clients without limiting access via user
authentication and a security policy.
Use the -noSecurityManager option to force the Network Server
to come up without a security manager. E.g.:
java org.apache.derby.drda.NetworkServerControl start -h localhost -noSecurityManager
