Kirk True updated KAFKA-15639:
------------------------------
    Description: 
The {{testResetPositionsProcessFailureIsIgnored}} test looks like this:

 
{code:java}
    @Test
    public void testResetPositionsProcessFailureIsIgnored() {
        doThrow(new 
NullPointerException()).when(offsetsRequestManager).resetPositionsIfNeeded();

        ResetPositionsApplicationEvent event = new 
ResetPositionsApplicationEvent();
        applicationEventsQueue.add(event);
        assertDoesNotThrow(() -> consumerNetworkThread.runOnce());

        
verify(applicationEventProcessor).process(any(ResetPositionsApplicationEvent.class));
    }
 {code}
 

[~junrao] asks:

 
{quote}Not sure if this is a useful test since 
{{offsetsRequestManager.resetPositionsIfNeeded()}} seems to never directly 
throw an exception?
{quote}
 

I commented out the doThrow line and it did not impact the test.
