First, let me state that I understand there are no official servers for Minecraft 1.2 (or previous non-Java versions)

The situation:
When connecting to a nemisys 1.0dev server (compatible with Minecraft PE 1.1) the server refuses the client connection, as it should.

The bug:
The client will continue to wait for resource pack synchronization from the server and become non-responsive, forcing the user to force-close Minecraft. The client remained stalled for nearly 3 minutes before being force closed.

Potential solution:
There probably should be a time-out on this for when official servers are opened up.

EDIT:
YAY! Cancel button! WOOT!
As of 1.2.0.11, this issue is now resolved. I am uncertain how to set to resolved.
