JVM arguments

ARI | Last updated: May 10, 2021 09:01AM UTC

I was trying installation to the Burp Suite Professional 2021.4.2 version. I get this error message: To run Burp Suite using Java 16 or above, please supply the following JVM argument: --illegal-access=permit How can I fix this issue?

Hi, Just to clarify, are you trying to install Burp or run the standalone Jar file version? If you are trying to run the standalone Jar file then we are aware of some issues with getting this to work with Java 16. The workaround would be to that add that argument to the command that you are using to run Burp i.e. you would use something like this to launch Burp: java -jar burpsuite_pro_v2021.4.2 --illegal-access=permit

Hi To clarify, are you still receiving the error message telling you to provide the JVM argument after including the JVM argument as part of your launch command? If you use the Platform version of Burp instead (for example, the Windows version), you shouldn't receive this error as Burp comes with an inbuilt version of Java.

Psyk3r | Last updated: Jun 22, 2021 08:12AM UTC

No i use the java format burpsuite and yes even after using 'java -jar burpsuite_community_v2021.5.3.jar --illegal-access=permit' i get the error .

in widows: open cmd command: cd C:\Users\and01\Desktop\burp pro - for example command: java.exe -javaagent:BurpSuiteLoader_v2021.5.jar --illegal-access=permit -noverify -jar burpsuite_pro_v2021.5.jar - change your version and you're done

had the same problem with v2021.8.4, for me what worked (windows) was adding "--illegal-access=permit" to the "C:\Users\username\AppData\Local\Programs\BurpSuitePro\BurpSuitePro.vmoptions" file

Hi Have you tried following the instructions in our documentation here: https://portswigger.net/burp/documentation/desktop/getting-started/launch-from-command-line What version of Java are you using? When you follow the launch instructions in the documentation, do you receive any specific error messages?

## WORKING FOR ME ON DEBIAN, UBUNTU, MACOS MONTEREY (MACBOOK PRO WITH M1 CPU) ## I have found that this works perfectly for me. Just open your terminal in Linux or Mac (Intel or M!) and type on the following: java -jar --illegal-access=permit burpsuite_community_v2021.9.1.jar And it worked perfectly! Thanks to everyone for all the advice. I couldn't have done it without your help. I just had to move the "--illegal-access=permit" from its location in the command. I was trying the other one (java -jar burpsuite_community_v2021.6.1.jar --illegal-access=permit) and it wasn't working. So I just moved around the "--illegal-access=permit" to after "java -jar" in the command to make it look like this: java -jar --illegal-access=permit burpsuite_community_v2021.9.1.jar Hope this helps! - TANK

BurpSuite Version Typo: *I was trying the other one (java -jar burpsuite_community_v2021.6.1.jar --illegal-access=permit) and it wasn't working. Should say: *I was trying the other one (java -jar burpsuite_community_v2021.9.1.jar --illegal-access=permit) and it wasn't working. - TANK

I had facing the same problem with java 17+ in my Parrot OS, and i found the solution by just change the default java version by running this command: . . . sudo update-alternatives --config java

Jsalim1901 | Last updated: Apr 07, 2022 03:48AM UTC
