Hi, The work to remove this warning from appearing is still in our development backlog. As noted in the original response, you can safely ignore the warning message and proceed with using Burp without any issues.

Hi, Just to clarify, are you seeing any other messages or errors being reported on the command line when this happens? Are you able to confirm what operating system you are running Burp on?

Hi, Firstly, can you confirm which versions of both Java and Burp you are using? Secondly, if you add the --diagnostics option to the command that you are using to run Burp (so something like 'java -jar burpsuite_pro_v2021.8.2.jar --diagnostics' depending upon the version of Burp that you are using) then this print your diagnostic information to the command line. Within this information there should be a 'Debug ID' value pair - are you able to supply this to us so that we can check to see if Burp is reporting back any errors to us. If you would prefer to send this information to us privately then please feel free to send us an email at support@portswigger.net.
