The test case _"Recovering offset from the last processed offset."_ in {{BasicMQTTSourceSuite}} fails sporadically.

I did repeated runs of that particular test and it failed 6 of 100 runs.
{code}
for i in `seq 100` ; do
  mvn scalatest:test -pl sql-streaming-mqtt -q \
    -Dsuites='*.BasicMQTTSourceSuite @ Recovering offset from the last processed offset.' | \
    grep -q "TEST FAILED" && echo "$i: failed"
done
1: failed
6: failed
22: failed
46: failed
77: failed
83: failed
{code}

The complete test suite BasicMQTTSourceSuite failed 56/100 times.
