-----------------------------------------

             Summary: System.FormatException in the Inactivity Monitor on Windos 8 with a
non US (European) Current Culture
                 Key: AMQNET-411
                 URL: https://issues.apache.org/jira/browse/AMQNET-411
             Project: ActiveMQ .Net
          Issue Type: Bug
          Components: NMS, Stomp
    Affects Versions: 1.5.3
         Environment: Windows 8, .NET Framework 2.0, ActiveMQ 5.6 with STOMP
            Reporter: Frederiek Lefebvre
            Assignee: Jim Gomes


I have a Windows 8 PC where the Current Culture is set to nl-BE. I'm communicating with an
ActiveMQ 5.6 Server using STOMP.

When I issue a connection.Start(), I get a ConnectionClosedException "The connection is already
closed!". When I enable tracing, I get another exception before that:

Debug: Exception received in the Inactivity Monitor: System.FormatException: Inp
ut string was not in a correct format.

Apparently the problem is with the parsing of the version of the incoming "CONNECTED" frame,
there the following code is executed:

                remoteWireFormatInfo.Version = Single.Parse(frame.RemoveProperty("version"));

The bug is easily resolved by changing that line with:

                remoteWireFormatInfo.Version = Single.Parse(frame.RemoveProperty("version"),
CultureInfo.InvariantCulture);

I didn't have this problem on my Windows 7 PC, although it is also set on nl-BE Culture.
