Hi, I get "java.lang.OutOfMemoryError: Java heap space" error when trying to setup a connection between jenkins server and a remote server. I've tried launching jenkins with "-Xmx4g" option, but this problem still occurs.

This error occurred when I clicked on the "Test Configuration" button.

This error occurs only when I check the box of "Use password authentication, or use a different key" and set my private key.

I've attached my settings and the full stack trace.
