Johnny, thank you for detailed response.

Please look at the comment. Do not use a file url to load the applet.
23-07-2013
You do not want to load your applet using a file url, as far as I know, it's been disallowed for security reasons. Is it only the Java2DTest applet which is not loading using a file url? Please use an http[s] url to load your applet. For a reference, please look at my attached screen shot.

Please provide a valid reason of resolving as cannot reproduce. Non-reproducibility on your system could also be a result of misconfiguration.

Johnny, could you please provide steps on how to debug the configuration issue? Michael, could you please attach full Java Console log to this issue?

I installed b98 on my windows, and could not reproduce the NPE. Could this be a configuration issue?
18-07-2013
We we load this demo ,It throws the same exception,but after we create .java.policy for all permission at the current user like: C:\Users\Administrator When we reload this case , it's passed.We marked it pass when we test jdk8b97.

I wonder is this is something to do with policy change for applets accessing file system resources ? How *eaxctly* was this test run ?
