Description Benjamin Muskalla CLA 2010-05-25 06:42:22 EDT 
When using EMF and RAP together and the display is disposed (either when closing the application or on session timeout), EMF tries to cleanup several images in a DisposeListener. In this special case, you cannot dispose the images in RAP as these are shared images.
This should initially be fixed on the RAP side (see bug 305136 ) but we will not have the time to fully implement this for the Helios release (but maybe for the service release). As this scenario throws an exception, I'd suggest to just comment out the dispose calls in the rap.emf.edit.ui bundle as a safe workaround (there will be no resource leaks).
