    1Clone fragment #1 returns variable f with type org.apache.tools.ant.types.FileList , while Clone fragment #2 returns variable p with type org.apache.tools.ant.types.PatternSet
    2The refactoring of the clones is infeasible, because classes org.apache.tools.ant.types.FileListTest and org.apache.tools.ant.types.PatternSetTest do not have a common superclass
