Tested JRE build : 7u6-b21/8-b255-2012-07-31_372
OS tested: winxp/win7

For trusted signer CAs , "Always trust content from this publisher" checkbox on the security warning dialog should be checked by default. But that's not true anymore with 7u6/jdk8
With 7u6/jdk8 this checkbox entry will be unchecked by default even for trusted signer CAs as a result of all such trusted certificates will not be stored inside the deployment security store by default and one can see security warning again by running the same applet/application again
It's regression under 7u6/jdk8 as compare to 7u5

Steps to reproduce:
1) Clear deployment security store
2) Install above mentioned 7u6 or jdk8 bundles
3) try to launch bugster as javaws htt://bugster.sfbay.sun.com
If on the security warning you can notice that "Always trust content from this publisher" is not checked by default then bug is reproduced
