    Preondition Violations
    Expression _comp.paste() cannot be parameterized, because it has dependencies to/from statements that will be extracted
    Expression _prefs.applyChanges() cannot be parameterized, because it has dependencies to/from statements that will be extracted
    Expression _comp.paste() is a void method call, and thus it cannot be parameterized
    Expression _prefs.applyChanges() is a void method call, and thus it cannot be parameterized
    Expression _comp cannot be unified with expression _prefs , because common superclass javax.swing.JComponent does not declare member(s) public void paste() , public void applyChanges()

    6The refactoring of the clones is infeasible, because classes net.sourceforge.squirrel_sql.fw.gui.TextPopupMenu.PasteAction and net.sourceforge.squirrel_sql.client.plugin.gui.PluginGlobalPreferencesTab do not have a common superclass
