A wild guess might be that you are getting "bad files" from some mirror.
I know there are certain safe guards built-in to p2 to avoid bad mirrors
and retry if a bad file is found, but, not sure its perfect. Especially
if the mirror has just some files that have been damaged.
The wiki page at
http://wiki.eclipse.org/Equinox/p2/p2.mirrorsURL
has instructions on
"Confirm_your_p2.mirrorsURL_works_with_p2_operations". In your case, you
are not trying to confirm that, but if you turn on debugging, you can
collect the extra output and see if the times you get one of those zero
length files its always from the same mirror? It'd be lot of output, but
if interested the brief instructions are to add these properties to your
..options file:
org.eclipse.equinox.p2.core/debug=true
org.eclipse.equinox.p2.core/artifacts/mirrors=true
If you found a mirror consistently serving bad files, you could open a bug (probably on Eclipse Foundation, community, Servers).

Perhaps a longshot, but I seem to remember that there were issues with
certain java versions and reading certain types of jar files - so, just
out of curiosity which OS and which Java are you running on?

Hi Dave,
This is difficult to help out with given that it's different files that
fail. I think the only way to really see what's wrong is to debug the
unpackToSibling method and trap the original CoreException and then
trace that back further.
Is the aggregation in it self sensitive or could you send it to me so
that can give it a try?
