The code which terminates the process when the enable_jit_debug argument is true is now duplicated. Before, the process was terminated before the screenshot attachment was submitted to erpt. Now, if the process is not an application, termination occurs prior to screenshot attachment is submitted; otherwise, application processes are terminated after the screenshot attachment is submitted.
