Hi, Can you clarify which version of Java you are trying to run Burp with?

Cloufish | Last updated: May 22, 2020 07:28AM UTC

openjdk version "1.8.0_242" OpenJDK Runtime Environment (build 1.8.0_242-b08) OpenJDK 64-Bit Server VM (build 25.242-b08, mixed mode)

Unfortunately, Burp, Version 2020.4.1 no longer supports using Java 8 so you would need to update your Java version in order for Burp to work. We have tested the latest version against OpenJDK 13.0.3 but versions 9 and above should work.
