> Please review this PR which removes usages of Applet within the corelibs tests. This includes both code usage as well as occurrences of the word.
> 
> There were more files found than the ones included in this PR, please see the comment on the JBS issue for the reason why they were not included. In general, I removed the file if the entirety was focused on Applet, otherwise I removed the portions applicable.
