I hate VMs. Repeated restarting of them wouldn't clear my ACC bootstrap. However, they were doing some electrical work in the server farm last night so the physical servers were powered down. That seems to have done it. A new copy of acc.war and it looks like I'm good to go.
Of course it could just as easily be that the error would not clear until I made a complete "****-of-self" by posting here and opening a case.
Thank you
Susan
