Hi Are you launching Burp from the command line or are you using the platform version of Burp? If you could try launching Burp from the command line, with the "--diagnostics" flag added, and send the output to support@portswigger.net that would be helpful. You can find more information about launching Burp from the command line here: https://portswigger.net/burp/documentation/desktop/getting-started/launching/command-line You can find our latest releases here: https://portswigger.net/burp/releases

Hello Hannah, I am facing the exact same problem when using Java 17. I then tried to add the "--illegal-access=permit" parameter, but get the same behavior. I also get a warning from Java: "OpenJDK 64-Bit Server VM warning: Ignoring option --illegal-access=permit; support was removed in 17.0". Java 17 is still in early access, but will be out next month as the first LTS version since Java 11. Is there any plan to support it in version 2021.9 of burp suite?

Can't seem to find an edit button. For reference, here is the JEP leading to the removal of illegal-access parameter: https://openjdk.java.net/jeps/403

Hi Unfortunately, Java 17 is not currently supported. We would recommend using 15 or 16 for now. When our 2021.9 release is out, there should be support for Java 17 and you can retry. Our platform/installer version of Burp comes prepackaged with its own JDK - you could use this in the meantime, instead of switching Java versions to launch Burp? It is currently packaged with OpenJDK 15.0.2.

This will definitely works for me in the meantime :) 2021.9 supporting it is a super news! Thank you.

Hi

You can use Java 17 with the latest versions of Burp.

If you launch the JAR file using Java 17, some instructions on additional arguments to add will display. Adding these additional arguments will let you use Burp with Java 17.

There may be some extension compatibility issues, so we would recommend initially loading Burp without any extensions enabled, and then enabling the ones that you wish to use with Burp.

You can find an example of the command used to launch Burp with Java 17 here:
java -jar --add-opens=java.desktop/javax.swing=ALL-UNNAMED --add-opens=java.base/java.lang=ALL-UNNAMED burpsuite_pro_v2021.10.2.jar
