    2Unmatched statement _popupMenu.add(action); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted
    3The refactoring of the clones is infeasible, because classes net.sourceforge.squirrel_sql.client.session.MessagePanel and net.sourceforge.squirrel_sql.client.session.mainpanel.objecttree.ObjectTreePanel do not have a common superclass
