Illegal reflective access by burp.fr8

lnxdork | Last updated: May 17, 2021 08:19PM UTC

I am running BurpSuite Professional v2021.5.1 Build 7814 and receive the following to the terminal while running BurpSuitePro: (The only extension loaded is turbo-intruder.) $ ./BurpSuitePro WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by burp.fr8 (file:/home/unknown/BurpSuitePro/burpsuite_pro.jar) to field javax.swing.plaf.basic.BasicPopupMenuUI$MenuKeyboardHelper.menuInputMap WARNING: Please consider reporting this to the maintainers of burp.fr8 WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations WARNING: All illegal access operations will be denied in a future release

Thanks for your message. I'd like to try and replicate this here, so far I'm not seeing quite the same behavior, to help us with this can you confirm the OS and Java version you are using, please? Also at what stage does the warning appear, does it appear as Burp is first loading and you are choosing which project file to use, or does this appear at a slightly later stage?
