Build Identifier: In a TableViewer I'm using, JFace always prints a warning about reentrant calls that looks like this: "Ignored reentrant call while viewer is busy. This is only logged once per viewer instance, but similar calls will still be ignored." I found out that this problem is caused by combining virtual tables with owner-draw. The warning message goes away if I override OwnerDrawLabelProvider#update(ViewerCell) and set some dummy text on the cell, similar to what is done in StyledCellLabelProvider. Reproducible: Always Steps to Reproduce: See the attached snippet.
