JRE warning magic number

Daniel | Last updated: Jan 20, 2023 09:00AM UTC

Hi, I use the Java version of Burp Suite Professional in Kali linux and on the first start it shows the well known message "Your JRE appears to be version 17.0.5 from Debian." When I check "Don't show again for this JRE" Burp adds a new setting to `.java/.userPrefs/burp/prefs.xml`. In my case `<entry key="suite.alertsdisabledforjre-1849443513" value="true"/>`. But after some time the magic number 1849443513 changes and the dialog appears again. Does someone know how this value is calculated? I could not find a way to receive a 10 digit java version number.

Hi This number is a hash of the vendor and version. I hope that helps. Please let me know if you have any further questions.
