I don't [yet] have an answer, but we have an app that supports SPNEGO and when we recently did a regression to certify our app for TC 9.x, SPNEGO broke. (Our app is also supported to run on WebSphere and WebLogic, and SPNEGO works fine on those). Installed on exact same server, same domain, configuration, ad nauseum --- use TC 8.0, no issue - stop 8.0, start TC 9.0 and SPNEGO is a no go. I did a diff of TC 8.0 / 9.0 source and don't see anything that jumps out at me to cause the issue, though there are changes. Anyway, we pushed the "investigate SPNEGO" Jira ticket to the bottom of the Backlog, so haven't pursued it further.
