Touch UI Sites page failing in AEM6 SP1

[Tim_Goodman_BTE]

In Touch UI for AEM6 SP1, I have a system that is repeatedly displaying no items on the Sites Menu.  The stack trace is below.  What's the best recovery?  Is it to delete compiled classes from /var or similar?

Hi Sham

yes, that bundle is active.  Should it be deactivated?

Thanks

[Sham_HC]

is bundle [1] active?

[1]  http://localhost:4502/system/console/bundles/com.adobe.cq.wcm.cq-wcm-launches-core

It should be active. Can you restart the system and verify?

[Tim_Goodman_BTE · Accepted solution]

Restarted, and problem remained.

I have reinstalled AEM (it was just a training instance), and the problem goes away.

I don't consider this a fix, so leaving this note here in case this issue pops up for others.  To me, it looks like some error occurred and AEM was unable to recover from some /var compiled class conflict
