latest supported Flink version (currently 1.14.4)? Flink 1.12 is no longer

> exception expected, but I cannot get it in jobmanager log. And I only get the
> exit code 1 in yarn log.

> h2. Relative code
> {code:java}
> // YarnApplicationClusterEntryPoint#main
> try {
> program = getPackagedProgram(configuration);
> } catch (Exception e) {
> LOG.error("Could not create application program.", e);
> Thread.sleep(10); // add this for test
> System.exit(1);
> }
> {code}
> h2. Log info
> * The ERROR log doesn't exist before Thread.sleep.
> !image-2022-03-25-16-35-39-531.png!
> * The ERROR log exists after Thread.sleep.
> !image-2022-03-25-16-35-46-528.png!
> h2. Reason
> System.exit() terminates the currently running Java Virtual Machine too fast
> to print the ERROR log.
> h2. Improvement
> I think we can print the ERROR log to jobmanager.err before call
> System.exit(1) so that we can get the exception info.
