Signing bundled JRE

[Steve Hannah]

I just tried submitting my Java app to the app store last night and
received an error message saying that my nested app bundle Java SE 7 is not
signed.  If, however, I sign the nested bundle, my app will no longer open.
 I get a Console log message saying that the application exited with Code:
2.

I am using the Oracle JDK 1.7.0_08 preview B03 and the appbundler ANT task
from Marco's fork.

Can anyone offer any advice on how to proceed?  (I've spent several hours
looking through the docs and trying different variations with the codesign
tool... but am rather stuck at this point).

Thanks in advance for any help.
