Bryan Pendleton commented on DERBY-6315:
----------------------------------------
Hi Ahsan,
The directory "system\wombat" is where the test harness creates a test database
for the tests to use.
You should be able to delete that directory and the tests will create a brand
new fresh test database the next time they are run.
It is possible that the crash that you printed in your stack trace represents a
bug in the test harness. The tests are supposed to run with a security policy
which allows Derby to read and write all the files in the database directory
("system\wombat"), but for some reason the security manager was refusing to let
the Derby recovery code read the file:
java.security.AccessControlException: access denied ("java.io.FilePermission"
"D:\Apache\Workspace\derby\system\wombat\jar\3d3b0068-0140-d54f-a291-0000589559b2.jar.G1377968313576"
"read")
I will have to do some research on what is going on here.
For the time being, please try deleting the directory
D:\Apache\Workspace\derby\system\wombat
and that should let you resume running the test program from Eclipse.
