Interesting tool. This looks like the Java equivalent of Facebook's Python taint analysis tool Pysa: https://pyre-check.org/docs/pysa-basics/.

From what I can tell by the documentation, it looks like Mariana's requires you to bring your own sources/sinks/sanitizers, so expect a lot of up front cost to integrate this into your toolchain. This as opposed to including commonly used rules or heuristics. Not a huge deal since users can write and share there own rules, but this looks like a framework for sophisticated static analysis and not a batteries included solution.
