I'm not sure it will be necessary to use JarProcessor for this.  The main 
benefit of using the JarProcessor is when doing modifications recursively 
on nested jars.  To verify during install, I think it's sufficient to 
verify the top level artifact, so recursion isn't needed. Also, since 
verification involves user participation(presenting certificates, asking 
if they trust the signer, etc), it may not work well as a processing step.

An aside: it's already confusing me to have IProcessStep in the jar 
processor bundle, and IProcessingStep in the artifact repository. We 
should probably rename the former to IJarProcessStep, or some such.

There is currently provisional API in the org.eclipse.osgi which is 
currently used by update to check the certificate trust and to verify the 
content of signed bundles. I assume the jar processor API can use an 
IProcessStep to which uses the API from the framework to perform this type 
of check? Or would verifying the signed content continue to be a separate 
step as it is today in update?

As for doing it now, is there any benefit to waiting? 
There is some amount of work that will depend on this change. Both 
update.core and pde.build will need to be updated after this change. As 
well, the p2.jarprocessor is considered HEAD for bug fixes (there is at 
least https://bugs.eclipse.org/bugs/show_bug.cgi?id=190064 that should be 
fixed). and clients would not get these fixes until it is promoted. 
While there is no particular rush on these changes, it is good to get 
anything that might block them out of the way.

In the long, there is no discussion about doing this change. However the
benefits of doing it right away are not clear to me.

As you may know, we used to have the JARProcessor embedded in the bowels 
of
Update manager.  Turns out that there are several uses for the processor
(pack200 support, signing, verifying, ...) and having this function as a
stand-alone bundle would be "a good thing"(tm).  So in the p2 work we did
just that and created org.eclipse.equinox.p2.jarprocessor.  Bug
      https://bugs.eclipse.org/bugs/show_bug.cgi?id=198564
talks about updating update to use the new processor.  Of course, the
current JarProcessor bundle is in the Equinox Incubator.  To date I think
we have avoided cases where we build the mainstream SDK based on content
from an incubator.

We have two choices, we can wait to move Update over or we can graduate 
the
current JARProcessor bundle.  Here I popose the latter since the code in
the bundle is unchanged from the original that shipped in 3.3.  All we are
doing is putting it in a separate bundle. The only thing at issue is the
shape of the API and that can evolve until the API freeze just as any 
other
bundle in HEAD.

So consider this a formal call for voting on graduating the
org.eclipse.equinox.p2.jarprocessor bundle.
+1 from me.
