Change Signature Method in Rename Class refactoring

[osmarleandro]

Summary

In the source code present in osmarleandro/RefactoringMiner@c088784 commit, I applied a single Rename Class refactoring to MoveAttributeRefactoring class. RefDiff detects the Rename Class refactoring, but also Change Signature Method refactoring.

Whereas to apply the Rename Class refactoring it is required to update its references. Therefore, is the instances of the Change Signature Method false positives?

Code example

Diff fragment between the commit osmarleandro/RefactoringMiner@c088784 and their parent.

Environment details

RefDiff 2.0

Steps to reproduce

1. Run RefDiff and give as input the commit osmarleandro/RefactoringMiner@c088784.

Actual results

CHANGE_SIGNATURE	{Method compatibleWith(MoveAttributeRefactoring) at src/gr/uom/java/xmi/diff/MoveOperationRefactoring.java:89}	{Method compatibleWith(MoveAttributeRefactoring_RENAMED) at src/gr/uom/java/xmi/diff/MoveOperationRefactoring.java:89})
CHANGE_SIGNATURE	{Method computeCompatibility(MoveAttributeRefactoring) at src/gr/uom/java/xmi/diff/UMLModelDiff.java:738}	{Method computeCompatibility(MoveAttributeRefactoring_RENAMED) at src/gr/uom/java/xmi/diff/UMLModelDiff.java:738})
RENAME	{Class MoveAttributeRefactoring at src/gr/uom/java/xmi/diff/MoveAttributeRefactoring.java:14}	{Class MoveAttributeRefactoring_RENAMED at src/gr/uom/java/xmi/diff/MoveAttributeRefactoring_RENAMED.java:14})

Expected results

A single instance of the Rename Class refactoring applied to MoveAttributeRefactoring class.
