Earlier today we had a web meeting hosted on www.livemeeting.com which had an option to join via the web, which turned out to use a Java applet. For some reason the system would not start. The first time a run was attempted we received the attached exceptions. In subsequent runs these exceptions did not occur, but the app also did not start. Switching to the old Java Plug-In worked. We need to investigate why this happened. It is possible that the most expedient way of investigating this will be to first fix all known minor JavaScript incompatibilities and then re-test. We might need to acquire a LiveOffice account in order to try hosting our own meetings for testing purposes.
