Summary: Possible failure to dispose GC can cause error messages

Description CLA 2010-02-26 08:10:54 EST 
Build Identifier: 3.5 and 3.6

This is confined to Mac OS X Cocoa.

On each of my GEF based editor RCP applications trying to run it under Cocoa, closing the application spits out the following to the console:

iMac java[880] <Error>: kCGErrorCannotComplete: CGSDeviceSynchronize: Invalid device window
iMac java[880] <Error>: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged.
iMac java[880] <Error>: kCGErrorCannotComplete: CGSDeviceSynchronize: Invalid device window
iMac java[880] <Error>: kCGErrorCannotComplete: CGSDeviceSynchronize: Invalid device window
iMac java[880] <Error>: kCGErrorCannotComplete: CGSDeviceSynchronize: Invalid device window

I found Bug #292780 which tells us that failing to dispose of a GC causes this on Cocoa.

So, I assume that somewhere in the GEF / Draw2d code this is happening. There could be cases where a GC object is created and the flow of operations means that the GC is not disposed.


Reproducible: Always

I'm not seeing this any more on Eclipse 3.7 I20110127-2034 and GEF 3.7 I201101272050.

Ok, resolving as WORKSFORME then.
