After upgrading to 1.4.6 there was about 5 minutes of successful gameplay, and then all players were disconnected after the server reported NullPointerException stack traces.
Subsequent attempts to connect are all unsuccessful. The server console reports:

This user was in creative mode. Another user in survival mode elicited the same response. The stack trace is identical on both operating systems (Linux and OSX).

One point I forgot to mention. One user told me he saw fireworks before being disconnected.
Yes, it's a dup. Searching for NPE didn't show up anything likely. I only learned about the fireworks after the initial report.
