How to disable SecurityManager in Derby?

[Rami Ojares / PDF-Comics Oy]

Hi,

I can't seem to figure out how to tell to derby (network server) not to 
use SecurityManager.
In the startup command there is no
**-Djava.security.manager**

property given to jvm. So the SecurityManager must be enabled at some 
point later in the code.
I am getting various SecurityManager related exceptions so that's how I 
know that it must be on.
