run.sh and run-helper.sh don't return the exit codes from Runner.Listener #4164
Description
Describe the bug
run.sh does not return the exit code from run-helper.sh. It addresses a return code of 2 and otherwise always returns 0. run-helper.sh does something similar. This makes the return code largely useless as you must always check stdout/err to see what happened.
Expected behavior
this line should be exit $returnCode. Similarly, several conditionals here return code 0 when they really shouldn't - at the very least, maybe this line should change?
That way, if I'm launching this from something expecting to report an error if execution did not succeed, it will actually know.
