    Preondition Violations
    Expression showSQLButton.addActionListener(listener) cannot be parameterized, because it has dependencies to/from statements that will be extracted
    Expression _tree.addToPopup(action) cannot be parameterized, because it has dependencies to/from statements that will be extracted
    Expression showSQLButton.addActionListener(listener) is a void method call, and thus it cannot be parameterized
    Expression _tree.addToPopup(action) is a void method call, and thus it cannot be parameterized
    Expression showSQLButton cannot be unified with expression _tree , because common superclass javax.swing.JComponent does not declare member(s) public void addActionListener(java.awt.event.ActionListener) , void addToPopup(javax.swing.Action)
