Re: [eclipse-dev] SWT Apps Crash on Carbon when launched from WebStart

[Marc Boorshtein <marc.boorshtein@xxxxxxxxxxxxxxx>]

After some investigation I have the following issues:

2.1.2  - SWT Based applications run VERY eradicly, eventually crashing.  
 It will work for a few seconds, and then become very un-responsive.    
Sometimes the responsivness would come back, sometimes it wouldn't   
This would occur both when executed from eclipse or when executed from  
a *.app package.

3M4 & 3M5 - SWT Based applications hang on startup

In all cases the app hangs when executed from a terminal

I am guessing that this is related to my event loop, so here it is:


while (!shell.isDisposed()) {
			if (!display.readAndDispatch())
				display.sleep();
}

Am I missing something?  The app works just fine on windows (though I  
haven't tested on linux or solaris yet).

Any help would be greatly appreciated.
