There are some classifications based on structure and syntax (e.g., [here](https://bitbucket.org/rjust/fault-localization-data/src/master/d4j_integration/README.md)). You can also find various dissections of the data set (see top-level README). While NPEs are fairly unambiguous and...

Hi @neelofarhassan, Currently, Defects4J does not provide a flag for fine-grained operator selection. Maybe Defects4J's mutation commands should also provide a flag for providing an mml file as input? That...

Can you please provide all commands necessary to reproduce this issue (presumably starting with defects4j checkout)? Thanks, René

I can reproduce the issue when explicitly changing the encoding to ASCII (i.e., changing the build file to use the `encoding` attribute for the javac task. Is it possible that...

Hi @jose, While D4J ships its own version of Ant (as part of the Major mutation framework), a system installation will take precedence. This is something we changed for version...

I was also able to reproduce this. Seems like a backward-compatibility issue (Java 7 vs. Java 8). We are about to update Major in Defects4J; I'll test the newer Major...
