----------------------------------------------------------------
The below modified code failed locally, however it failed in the line 215.
Still investigating.
Check:
{code}
runAcidMetricService();
long now = System.currentTimeMillis();
long oldDiff = (now - oldStart)/1000;
long youngDiff = (now - youngStart)/1000;
long threshold = 1000;
int intValue =
Metrics.getOrCreateGauge(MetricsConstants.OLDEST_READY_FOR_CLEANING_AGE).intValue();
System.err.println("Now: " + now);
System.err.println("Old start: " + oldStart);
System.err.println("Young start: " + youngStart);
System.err.println("Old diff: " + oldDiff);
System.err.println("Young diff: " + youngDiff);
System.err.println("Age: " + intValue);
boolean assertValue = (intValue <= (oldDiff + threshold));
Assert.assertTrue(assertValue);
{code}
Output
{code}
Now: 1638863282765
Old start: 1638863245187
Young start: 1638863263762
Old diff: 37 (diff 37578)
Young diff: 19 (19003)
Age: 18 (which is calculated and rounded inside the runAcidMetricsService)
