[news.eclipse.technology.emft] [EMF Compare] possible bug comparing reso

["Jose Hernandez" <jose.hernandez@xxxxxxxxxxxxxxxxxxx>]

Hi,

I have encountered a problem in EMF compare whereby an index out of bounds 
(-1) exception in thrown in resourceURISimilatity when comparing in memory 
(non-persisted) resources.  My resources are created in this way:

ResourceSet resourceSet = new ResourceSetImpl();
Resource resource = resourceSet.createResource(URI.createURI(""));
EList<EObject> contents = resource.getContents();
contents.add(emfModel);

Does anyone know whether this is a known issue?  If so, is there are fix for 
it?

java.lang.ArrayIndexOutOfBoundsException: -1
