[Beta v2.0.03beta] Warning when starting Burp on OSX

Sylvain | Last updated: Sep 04, 2018 05:12AM UTC

Hi, Just started testing the new beta and I really like the new dashboard look. I am running it on a fully updated OSX with fully updated JAVA. Everything seems to work fine (although slow, and I will add another bug entry). However, when I start burp using java -jar on a command prompt from a user with admin privilege (but not using sudo java -jar... not sure if that's required), I am getting those warnings: ------------------------ WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by burp.fr_ (file:/Users/xorsum/Private/svain-xor/Software/Burp/burpsuite_pro_v2.0.01beta.jar) to field javax.crypto.JceSecurity.isRestricted WARNING: Please consider reporting this to the maintainers of burp.fr_ 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 Your JRE appears to be version 10.0.2 from Oracle Corporation Burp has not been fully tested on this platform and you may experience problems. ------------------ So it would seem there is an "illegal-access" being done that may not work in future... will it be a problem? And that the standard/official JRE may not be supported/tested... is that a problem? and if so what JRE should I be using... I prefer to use the latest and official version. Please note that for my day to day operation I just use the installed non beta version of burp, so I don't see any warnings as I do not start it from the command prompt. Thanks. Sylvain.

Thanks for letting us know about this. The recommended Java version for Burp is the latest Java 8. Informally, it appears that almost everything works with Java 9 and 10, but we have some work to do to tidy up minor issues like this warning.
