The fix for 6369226 required adding a "read" FilePermission for the "../../test.props" file to several tests' "group.security.policy" because ActivationLibrary's static initializer now requires that permission. One test's group.security.policy file that should have been updated was not:

test/java/rmi/activation/ActivationGroupDesc/useExecPolicy/group.security.policy

but fortunately that omission does not seem to result in the test failing. It is, however, causing a spurious ExceptionInInitializerError/SecurityException to be logged in the test output, so it should be fixed.
