DWR in Monitorplugin fails, causes statistics to be inaccessible

Hi slicer321, feel free to debug and write a patch, that fixes this issue with 1.1.4. I would really like to review it. I for myself don't care much about the monitoring plugin, but want to push the next release and have a working plugin for the most plattforms.

Ok, I downgraded the DWR version to 1.1.3 which works fine for me, so I think we don't need to go back to 1.1.1. Please report if someone has an issue with that.

To confirm previous findings, I do see the error messages in the error.log file, but in contrast the stats-dashboard.jsp is displays properly on my server, e.g Server->Statistics does show graphs "Current Users", "Active Conversations", and so properly. Was there a missing function as well? It may be useful to debug this so that dwr can be updated to latest, but at the same time I believe all the other dependent plugins work fine without updating. My configuration is as follows. Also note I did update dwr.jar everywhere to 1.1.4 to be consistent across all the plugins.

Openfire 3.6.3, rev.10959.
Plugins
Monitoring Service 1.1.1
Fastpath Service 4.1.0
Fastpath Webchat 4.0.0
Search 1.4.3

Dwr.jar 1.1.4
Jetty libs 6.1.18
Xstream 1.3.1
Base OS is FreeBSD 7.2-RELEASE-p4 FreeBSD 7.2-RELEASE-p4 amd64.
Java JDK version is Diablo Java(TM) SE Runtime Environment (build 1.6.0_07-b02).

If the original version (1.1.1) doesn't have the problem, I vote for rolling back.

Oh, I'm not sure about the assumption of the two identical DWR libs, it seems before they were also identical (version 1.1.1). But adding the monitoring libs to the ClassLoader of Openfire would fix the issue.
