thx.

1.5.0 is an old version. can you try latest 1.6.1, to see if the problem might already been solved? (that part of the code has got lot of refactoring in the last year...)

@arcuri82 Thank you again, I tried running the latest version: 1.6.1, and I succeeded :-)
However, before the final result, EvoMaster returned some WARN's (are they very concerning? Could they have significantly affected the final result?):

And the final result had some odd variables, like Bytecode line coverage: NaN% and a large number of potential faults.

I'm trying to run EM with --maxtime 120m now

After this, EM returns a bug:

hi @victorhugofr

thanks. few things:

1. you can ignore those WARN messages (those are just internal details)

2. the 0% line coverage is weird... are you sure that the "br.rest" package name is correct? In any case, we should provide a better error/warning message in those cases

3. the last error reminds me of a known issue, which might already had been fixed in current SNAPSHOT. We are going to have a new release soon (hopefully within 1-2 weeks, after fixing some other bugs)

[arcuri82]

hi @victorhugofr ,

could you please check if you still get the same issue with the latest 2.0.0 release? (we have made several fixes with might be related to the issues you experienced)

[arcuri82]

closed as it might be fixed, and no further info has been provided
