AccessControlException when running junit tests under the ant harness in ant 1.7.0

                 Key: DERBY-3153
                 URL: https://issues.apache.org/jira/browse/DERBY-3153
             Project: Derby
          Issue Type: Bug
          Components: Test
    Affects Versions:
            Reporter: Rick Hillegas

The following AccessControlException occurs on junit tests run under the ant harness if the
ant version is 1.7.0:

    [junit] Running org.apache.derbyTesting.functionTests.tests.jdbcapi.AutoloadTest
    [junit] Tests run: 3, Failures: 0, Errors: 1, Time elapsed: 1.029 sec

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.
