INFO:root:Successfully stopped experiment.

What is affected by this bug?

Currently, it will not affect final report generating. For others, not sure about it for now.
The experiment seems run successfully. It only shows up at the very end.

When does this occur?

It shows up at the end of whole execution, after

...
INFO:root:Done measuring all trials.
INFO:root:Finished measuring.

and before

INFO:root:Successfully stopped experiment.

Where on the platform does it happen?

How do we replicate the issue?

It mainly refers to the commands described in here.
The difference is the command to run:

PYTHONPATH=. python3 experiment/run_experiment.py --experiment-config experiment-config.yaml --benchmarks zlib_zlib_uncompress_fuzzer jsoncpp_jsoncpp_fuzzer --experiment-name multitest --fuzzers afl aflfast fairfuzz

Expected behavior

No such error reporting at last.

Other

It has no effect for generating reports.
