[xmlblaster] Problems shutting down xmlBlaster with persistent topics

[Aaron Silinskas <aaron at mindwidgets.com>]

Hello,
  It seems when I subscribe to a topic with 
SubscribeQos.setPersistent(true), then unsubscribe, I get a warning and 
exception when shutting down xmlBlaster. It seems the disconnect is 
erasing the topic, which tries to unsubscribe first without checking if 
the subscription still exists.

When xmlBlaster is started again, I get these warnings on start-up:
