You could have actually done what you suggested and searched for a bug.

My bad!

   "support for signed zip file with plug-in applets"

Yes. That pretty much sums up the results we are
seeing, and confirms that handling of Zip files is
different for 1.5 and 1.6/6.0.

However, although it is currently listed as an
'In progress, bug' - I find this comment confusing..
"Evaluation: in 6.0, we will only read certficiates
for JAR files."

That *almost* implies to me 'we changed our minds,
and tightened the spec. without telling anyone - it will
stay that way - but we might document it somewhere'
(perhaps I read it wrong..)

Do you read that bug report as meaning that Sun
intends to change the behaviour of the 6.0 Plug-In
to again support signed Zip files?

Here is the exception if that helps any.
