Is it missing the Rename Method refactoring?

[osmarleandro]

Summary

In the source code present in osmarleandro/RefactoringMiner@cf32531 commit, I applied a single Rename Method refactoring to getRegex() method in the RefactoringType class. RefDiff yields an empty list of refactoring. Is it missing this true instance of Rename Method refactoring?

Code example

Diff fragment between the commit osmarleandro/RefactoringMiner@cf32531 and their parent.
