I think what you need to do is use a source code parser like javaparser to do this.

For every java source file, parse it to a CompilationUnit, create a Visitor, probably using ModifierVisitorAdapter as base class, and override (at least) visit(MethodCallExpr, arg). Then write the changed CompilationUnit to a new File and do a diff afterwards.

I would advise against changing the original source file, but creating a shadow file tree may me a good idea (e.g. old file: src/main/java/com/mycompany/MyClass.java, new file src/main/refactored/com/mycompany/MyClass.java, that way you can diff the entire directories).
