This type of select/deselect behavior is not entirely uncommon.

Although I generally do agree with you on not trying to "outsmart"
native widget behavior, sometimes there is no other way.

For example - our application needs exactly this behavior because it is
expected to be used in touch-only devices which do not have a notion of
Ctrl key modifier.

Ability to select and then de-select a table item by "toggling" it needs
to be provided explicitly and native widget set should not try to fight
my decision to do so.

From my POV the behavior where explicitly de-selected item gets
magically re-selected later without explicit user- or programmer
intervention is a bug of the platform.

I've filed a bug report to SWT for this issue:
