7.5 Post upgrade issue

Greetings All,

I recently upgraded from 7.3 -> 7.5. Everyting looked OK until I attempted to add (discover) an additional device. I'm getting a "There was a problem with your request, please try again later" message. After some google research, it looked like the April hotfix might solve the problem. That's been installed but the issue remains. All other functionality appears to be working fine. I did see an article about missing Java packages but it seems a bit of a hack, IMHO.

Anyone run into this?

Thanks.
