The error occurs during JMRI startup after specifying Skip message in future for UserName has been moved message.
The following was added to the UserPrefs XML file:
<classPreferences class="jmri.jmrit.beantable.BeanTableDataModel"> <reminderPrompts> <reminder>remindSaveReLoad</reminder> </reminderPrompts> </classPreferences>
The Preferences >> Messages section did not have an option to reset this so I manually removed it and the error no longer occurs.
Using the PanelPro application, JMRI 3.5.2.
