Steps to reproduce:
1. Install the latest 8 nightly (#645) on win7-x86
2. Import cert http://sqeweb.us.oracle.com/net/sqenfs-1/export1/comp/jsn/users/stephen/deployment_stuff/do.NOT.remove.me/bugs/UserDecisionPersistence/lib/validcert.cert to deployment trusted Signer CA store so the applets will be regarded as CA-signed.
3. Open http://sqeweb.us.oracle.com/net/sqenfs-1/export1/comp/jsn/users/stephen/deployment_stuff/do.NOT.remove.me/bugs/UserDecisionPersistence/html/testMulitpleCASignedApplets.html
4. There will be a CA-Signed security dialog asking for "unrestricted access", accept it.
5. If you see following exception in java console, then the issue is reproduced.
