Gatling not sending client cert at all

[Ethan Allen]

Hello, I've been beating my head against the wall.  TL;DR is that for some reason Gatling will not send, to my understanding, the client cert at all.

Some details:

1. Project is a gatling-maven-plugin project
2. Client cert is signed by an internal CA
3. Enabling -Djavax.net.debug=all for gatling-maven-plugin reveals a ton of SSL information and from what I can glean it doesn't send my cert
4. If I purposely put in the wrong password OR bad file name, the gatling.conf is read and an exception is thrown.
5. Based on the nature of the infrastructure the server will NOT reject due to no client cert but rather the application will have permission/entitlement issues and respond with error when not present
6. My Scala skills are weak

1. Is there some sort of standard regarding the JKS file that isn't well documented that will eliminate gatling from sending it?  
2. Is there any sort of real GitHub project with test JKS that one could pull apart to suss out the differences and flaws in their own project?
   
3. Is there any sort of debug information I should be looking for as to why the cert is not being sent?
4. What else can I do to get unblocked?  What information can I provide?

Thanks!

We did the following to get past this:

1. Created a new trust store that had the client cert and grandfather cert that signed the server cert
2. Created a new key store that just had the client private key
3. Made sure both had the same password (I don't know why this would matter)
4. Dont rename the keystore once created :)
