Java Authentication on <cftree> Error.

Hello,

I work for a company that has a very old application that runs with CF7 on a SunONE server.  Yesterday we starting getting the notice that our Java plugin was out of date company wide on a specific page with a <CFTree> tag.  After updating the Java browser plugin we now get a Java Authentication Required username and password window. No one has any idea where this login popup is coming from. Updating this application is not an option at this time due to cost and age of the application.

Anyone have any ideas?

Here is what the login popup looks like for reference:

Thanks,
