This only happens on Chrome and Firefox. Before throwing this exception, the browser reports a security warning dialog that says
"This application has been found to contain a potentially unsafe combination of both signed and unsigned components (code and/or resources)
This situation may indicate a security risk unless it was intended by the application vendor (unusual).
Blocking potentially unsafe components from running (by clicking the Yes button) will protect the data on your computer, but may cause the application to fail.
This action is recommended if you are unfamiliar with the application or the website from which it was accessed.
Allowing potentially unsafe components to run (by clicking the No button) could compromise data on your computer.
To reduce risk, Java will run trusted components where available."
Clicking both Yes and No results in the abovementioned error message
ERROR: Throwing exception: oracle.osl.lt.audio.LTCommunicationException; Error code: 100004; Message: Failed to get play list from Content server. Reason: Unexpected end of file from server

The audio applet was working in 3.1.2 but has never worked for us in 3.1.3.
We are also looking for help in this area - thought I would reply to your thread as it seems quite similar.
