I’d like to thank everyone who helped spread the word on the new Code Signing requirements and guidelines starting with 7u21. In particular, Markus Eisele did a fantastic job with his blog, and also an article in Heise Developer (in German) – thanks @myfear!
We’ve just added two new FAQ questions to the OTN article on Code Signing in response to a two particularly frequent questions. The first is in response to questions around applet signing, and in particular the fact that prior to 7u21 signed apps were assumed to want full permissions, and unsigned were assumed to want to be sand-boxed. See the FAQ “How has this changed the underlying security model of Java applications in the browser?” for more information.
Both questions contain links to the product documentation with additional information for developers and admins.
