Myrna van Lunteren commented on DERBY-1241:
-------------------------------------------
I tried my scenario (see DERBY-1598, marked as duplicate to this one) with
10.1.3.1 (build 417277) and instead of a java.security.AccessControlException I
get a NullPointerException:
---------10.1.3.1 derby.log-(sorry, insane jars-no line numbers)----------

-----------------------------------------
I guess getting a security exception is an improvement of sorts.
Subsequent connects in the same session in 10.1.3.1 give
ERROR 08004: The application server rejected establishment of the connection.
An attempt was made to access a database, tstdb101, which was not found.
In my scenario, the workaround for the 10.2 problem (adding permissions to
read, write, delete under derby.system.home already granted to derby.jar also
to derbynet.jar) also gets around the 10.1.3.1 NPE./08004; and thereafter, I
can reset the policy file and bounce the server and reconnect as much as I
want.
And yes, this trick works with 10.2 also.
