I'm observing some strange behaviour in my RCP app.
Is this warning meaningful, i.e. does it represent a programming error
when using the TableViewer?:

Ignored reentrant call while viewer is busy. This is only logged once per
viewer instance, but similar calls will still be ignored.

Hi,

Yes - it looks like you are modifying the table while you are modifying
it :-) so it looks like you are doing something illegal.
