To use this extension you will need to start Burp with the required or later Java version.

Sounds like you're on old Java. Try updating Java, or using the platform installer for Burp

dorkerdevil commented 5 years ago

my java is in the newest version

dorkerdevil commented 5 years ago

i think i have to lower down the version probably, will update

Same issue here. Running JRE 8 update 221 on Windows 10 x64 (1803) which is the latest available for download.

Java 8 is beyond end of life. I'll look into removing this dependency if it's straightforward but you need to use Java 11+, or Burp's platform installer.
