Subject [jira] Updated: (DERBY-3153) AccessControlException when running junit tests under the ant harness in ant 1.7.0
Date Fri, 26 Oct 2007 14:36:50 GMT

     [ https://issues.apache.org/jira/browse/DERBY-3153?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Rick Hillegas updated DERBY-3153:

    Attachment: derby-3153-sampleFix-aa.diff

Attaching derby-3153-sampleFix-aa.diff. This adds some more permissions to the default test
policy, derby_tests.policy. With those permissions, I am able to start up the junit tests
under the ant harness under ant 1.7.0 and they start out running without errors. That is,
I don't see any initial security exceptions.

I think this could be the basis of a fix for this bug. The additional permissions would need
to be propagated to the other policy files used by the tests and, of course, some time would
have to be spent verifying that the tests run cleanly.

> I haven't looked at the ant source, but here is my theory about what is going on:
> 1) Ant 1.7.0 is trying to write a file to the directory where the ant script lives
> 2) The write is not wrapped in a privileged block
> 3) So all code domains above it on the stack need to be granted write permission on the
directory where the ant script lives
> I will attach a modified version of derby_tests.policy which allows me to start up the
tests without tripping across this security exception.
