When you click on Window->Preferences->WindowBuilder->SWT->Layout->FormLayout I get an error.

This error has been happening to me for years now and with many different version of eclipse and windowbuilder.
The last version that works for me is the Mars.2 version.

Can someone correct or tell how to fix this?

Thanks
