    Unmatched statement copyFile(sourceFile,toDir); cannot be moved before or after the extracted code, because it has dependencies to/from statements that will be extracted
    Unmatched statement copyFile(sourceFile,toDir); cannot be moved before or after the extracted code, because it throws exception(s) that should be caught by a try block that will be extracted

    6Clone fragment #1 returns variable doc with type javax.swing.text.Document , while Clone fragment #2 returns variable sourceFile with type net.sourceforge.squirrel_sql.fw.util.FileWrapper
    7The refactoring of the clones is infeasible, because the number of macthed statements is equal to zero
