>             Project: Apache NiFi
>          Issue Type: Bug
>    Affects Versions: 2.0.0-M4
>            Reporter: Bryan Bende
>            Assignee: Bryan Bende
>            Priority: Major
>             Fix For: 1.28.0, 2.0.0-M5
>
>          Time Spent: 1h
>  Remaining Estimate: 0h
>
> The JettyServer start method has a try/catch with:
> {code:java}
> } catch (Exception ex) {
>     startUpFailure(ex);
> } {code}
> Some errors that can happen do not extend Exception so they are not caught 
> here, and as a result they do not go into the helper method which calls 
> System.exit, so the NiFi process and JettyServer remain started, but in a 
> strange non-fully working state.
> It will ultimately bounce to the NiFi main method which just logs the error, 
> but doesn't exit:
> {code:java}
> try {
>     NiFiProperties properties = 
> convertArgumentsToValidatedNiFiProperties(args);
>     new NiFi(properties);
> } catch (final Throwable t) {
>     LOGGER.error("Failure to launch NiFi", t);
> } {code}
