.jar warning

Good day. I get the following in the command prompt when opening .jar version 2021.12: WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by burp.a9u (file:/C:/Users/XXXXX/Desktop/burpsuite_pro_v2021.12.jar) to method sun.security.pkcs11.wrapper.PKCS11.getInstance(java.lang.String,java.lang.String,sun.security.pkcs11.wrapper.CK_C_INITIALIZE_ARGS,booleon) WARNING: Please consider reporting this to the maintainers of burp.a9u So I don't know if this is the correct forum or not. I am using Java 11.0.6. Windows Server 2016

Hi Kathleen, The warnings are expected and can be safely ignored. Does Burp load successfully for you when you launch it via command prompt?

Yes, it does. We are having issues with Burp only sending one certificate and not the entire certificate chain. Thought that might have something to do with it.

Hi Kathleen, Is the certificate issue one that you (or one of your colleagues) is already in discussion with us with?

Kathleen | Last updated: Jan 24, 2022 01:50PM UTC

Yes, it is. Was wondering if you know how to change the jdk.tls.maxCertificateChainLength? Maybe increasing that will help?
