I can answer half your question - maybe with clarification I'll figure out the rest.
Actually, based on the exception, it looks like the chrriis.dj.nativeswing.swtimpl.core. SWTNativeComponent class caused the problem and WindowBuilder trapped the error for you. I assume it showed you this on the Design page (as it is designed to do) and did not actually "crash".
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
