Your SCCM/WSUS server is unable to download the patches from the vendor. I tested this in my environment a few minutes ago and I couldn't reproduce the issue.
Are you going through a proxy? (need to make an exception?)
Have you been able to publish Java patches in the past?
Are you able to download these patches manually from the SCCM/WSUS server?
(These were taken directly from my AutoPublish.log)
