The error is caused by the increase security in Freeplane 1.5.20.
The method getNodeAttributeTableModel is used in a minor functionality which sets the column width of the attribute value to a certain minimum width. This functionality can be removed, since it is possible to change default attribute column width in the Freeplane settings menu.
It should be checked whether other imports of Freeplane code leads to similar illegal access errors.
