Vlasov Igor commented on DERBY-6848:
------------------------------------

In summary
Derby 10.10 run always ( through Netbeans or .bat file.)
I can run derbyNetworkServer 10.11 or 10.12  through Netbeans 8.0.2 on jre8_25.
BUT derbyNetworkServer 10.11 or 10.12  do not run through .bat file.
I  do not understand why I see sush behaviour.


On other machine jre8_66 and  Netbeans 8.1 cannot  start 10.11 or 10.12 version 
of derby, but 10.10 is started. 
And 10.10 starts through .bat file.

Solution
I  downloaded source of 10.12 and extracted sourcecode of derbynet.jar. Then I 
made my own version of org.apache.derby.drda.NetworkServerControl with 
corrected method needsSecurityManager (it always run  in insecure mode) and 
replaced the original file in  jar.

Now  I can run derby 10.12. through .bat file or Netbeans 8.1. This was my 
target.

Seems this issue is very rare.
You may close it If you want.
