Burp jar not loading

Marius | Last updated: Dec 22, 2022 02:34PM UTC

Starting with 2022.12.2 I get this error when I try to start Burp. Running Ubuntu 20.04 and openjdk version "11.0.17" 2022-10-18 OpenJDK Runtime Environment (build 11.0.17+8-post-Ubuntu-1ubuntu220.04) OpenJDK 64-Bit Server VM (build 11.0.17+8-post-Ubuntu-1ubuntu220.04, mixed mode, sharing) Error: LinkageError occurred while loading main class burp.StartBurp java.lang.UnsupportedClassVersionError: burp/StartBurp has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 55.0 Any advise on what to do? Thank you.

Hi Burp Suite now requires Java 17 or later to run. https://portswigger.net/burp/releases/professional-community-2022-12-4?requestededition=professional Please let us know if you have any issues launching Burp using Java 17.

Hi Can you please tell us a bit more about your setup? - Which OS are you using? - Are you having issues with both the installer version of Burp and launching Burp using the JAR file from the CLI? - If you are launching the JAR file from the CLI, can you please confirm the Java version and the command you are using to launch Burp?

Hi, The error means that Burp cannot run with the version of Java that you are using. Are you able to confirm what version of Burp you are trying to run so that we can assist you further with this (if you are attempting to run a later version of Burp then it is likely that you would need to use Java 17 at a minimum but if you can confirm the exact version of Burp then we can provide a definitive answer).

Hello ! How can check the version Burpsuite ? I tried it like this: ┌──(kali㉿kali)-[/usr/bin] └─$ burpsuite --version Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=on -Dswing.aatext=true Error: LinkageError occurred while loading main class burp.StartBurp java.lang.UnsupportedClassVersionError: burp/StartBurp has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 55.0

Hi, The error would appear to indicate that you need to use Java 17 - are you able to obtain this and then try and run the version of Burp that you have?
