Description Stefan Weiser CLA 2021-12-09 01:23:16 EST 
Each instance of org.eclipse.nebula.widgets.grid.Grid creates a GridColumn for the row header: rowHeadersColumn. This column is defined as internal column and therefore not taken over into the list of Grid.columns (also see Grid.isInternalColumn). When the Grid gets disposed (see Grid.onDispose(Event)) all non-internal columns gets disposed in a foreach loop but the rowHeadersColumn does not get disposed. Therefore, each instance of Grid is leaking in the memory.

I simply fixed this by calling rowHeadersColumn.dispose() in Grid.onDispose(Event). 

This occurs on each Grid. It can easily be reproduced by creating an empty Grid and disposing it again.
