I have set the option to true:

        EntryPoint.useOptionsFile = true;

Hi @andre15silva

Thank you for testing, I did not update the binaries, therefore the options were not included in the fresh JVM.

I also made a test and updated the README.

Best.

[andre15silva]

Great!

Flacoco's test suite is all green now! :tada:

[danglotb]

Great news! I think this is ready to be merged

@monperrus could merge it please?

Best.

[monperrus]

Thanks a lot @danglotb
