I think as part of our testing, we need to test UI pages going over https, too. I came across this JIRA ( https://jira.jboss.org/jira/browse/RF-5624 ) which tells me we need to be exercising the entire UI over https to catch any errors in the JSF/Seam framework, especially including file upload pages (like the plugins UI page and the content UI pages).
I have run the automation against a linux/postgres rev3078 server with https. Everything looks normal. I'll do some specific testing on file upload pages now.
Tested upload pages for content and plugins, works fine over https.
