Extract and Move Method in Rename Method refactoring

[osmarleandro]

Summary

In the source code present in osmarleandro/RefactoringMiner@38b41e6 commit, I applied a single Rename Method refactoring to isParameter() method in the VariableDeclaration class. RefDiff yields four instances of Extract and Move Method refactoring.

Environment details

RefDiff 2.0

Steps to reproduce

1. Run RefDiff and give as input the commit osmarleandro/RefactoringMiner@38b41e6.

Actual results

EXTRACT_MOVE	{Method allVariablesAreParameters() at src/gr/uom/java/xmi/diff/SplitVariableRefactoring.java:52}	{Method isParameter_RENAMED() at src/gr/uom/java/xmi/decomposition/VariableDeclaration.java:118})
EXTRACT_MOVE	{Method getRefactoringType() at src/gr/uom/java/xmi/diff/RenameVariableRefactoring.java:36}	{Method isParameter_RENAMED() at src/gr/uom/java/xmi/decomposition/VariableDeclaration.java:118})
EXTRACT_MOVE	{Method allVariablesAreParameters() at src/gr/uom/java/xmi/diff/MergeVariableRefactoring.java:52}	{Method isParameter_RENAMED() at src/gr/uom/java/xmi/decomposition/VariableDeclaration.java:118})
EXTRACT_MOVE	{Method getRefactoringType() at src/gr/uom/java/xmi/diff/ChangeVariableTypeRefactoring.java:42}	{Method isParameter_RENAMED() at src/gr/uom/java/xmi/decomposition/VariableDeclaration.java:118})

Expected results

A single instance of the Rename Method refactoring applied to isParameter() method in the VariableDeclaration class.
