Description

NIFI-2933 changed StandardPublicPort to use the 'processGroup' variable passed as its constructor argument at the EventReporter.reportEvent() method, but that variable is null when a public port is instantiated.

EventReporter.reportEvent() should get the current ProcessGroup by calling getProcessGroup() method each time.

If an error occurred while a public port is processing request, it fails to report a bulletin event due to this NullPointerException. Due to this issue, public ports can not report error detail to users with bulletin messages like following screenshot.
