I have Java 7 installed for Ubuntu 12.04 and I have IcedTea installed in Firefox (33.0). Some Java plugins are not working correctly. For example: starting from the IcedTea-Web-Tests (see the IcedTea wiki) I tried two tests:
The WebEx test session (http://www.webex.com/test-meeting.html). This runs correctly once. Subsequent attempts to run this without restarting the browser will fail.
The Java version verification (http://www.java.com/en/download/installed.jsp). This does not run.
Failure is indicated by a big grey box and nothing happening (sometimes I get prompted to run the applet first, but then nothing happens). I turned on logging and checked the log files in ~/.icedtea/logs/ Whenever something fails, as above, the reported error is
java.lang.UnsatisfiedLinkError: Native Library /usr/lib/jvm/java-7-openjdk-i386/jre/lib/i386/libjawt.so already loaded in another classloader

I can't find any specific help for this error, does anyone have any ideas?
