Florian Schmidt updated APEXCORE-776:
-------------------------------------
Description:
When launching an application, killing it immediately and trying to restart it
with {{-originalAppId}}, the following stacktrace is shown. I *assume* that
this is because the app never reached running state but was killed in submitted
/ accepted step.
Expected behavior: Better error message as to why this error occurs.
