[amandelpie]

@Markoutte did you have this exception?

[Markoutte]

Looks like yes

[amandelpie]

When I run it for Stats.of(doubles) method

The error which found is here ExecutionDistance: row 28 distances.last().last().toDouble()

Some context: If we use concrete execution not in the end of the analysis, the engine produces a UtExecution with empty paths, because ConcreteExecutor doesn't know hot to translate bytecode to soot.

@sergeypospelov thanks, looks like now we have a temporary solution and it should be revisited in the nearest future

Fixed in the #567
