      Hi, I'm testing the bacnet in mango2.4 (latest at the date)

      java: ```

      java -version
      java version "1.7.0_55"
      OpenJDK Runtime Environment (IcedTea 2.4.7) (7u55-2.4.7-1~deb7u1)
      OpenJDK 64-Bit Server VM (build 24.51-b03, mixed mode)

      
i add the data point, all works,  but looks like it fails to subscribe to COV, and throws a critical

      Cannot send a request in the socket listener thread

      but nothing on the console,

and when i force the point refresh it throws the "DWR invocation exception" in the console,
stack trace:

            That is very odd, I'm really not sure why you are getting that. We made lots of improvements to the BACnet module in this version and it seems to be very stable in all our testing and usage.
