The test sets a security manager to ensure that appropriate permission
checks are performed. It expects to be denied reflective access to a
private field in a different package. Access, to this field, is granted
if the code has RuntimePermission "accessDeclaredMembers". This
permission is not expected, but the default policy implementation
combines the java.home/lib/security/java.policy and
user.home/.java.policy. So if a policy file, .java.policy, with
RuntimePermission "accessDeclaredMembers", just happens to be in the
users home directory when this test is run, it will fail as above.
The solution, trivially, is for the test to set its own policy, and
remove any dependency on the default policy.
