Description Fabien Giquel CLA 2010-04-22 11:56:43 EDT 
When using some CDO, method JDTVisitor.deepRemove() throws some ArrayIndexOutOfBoundsException.

The problem does not occur when using XMI and incremental discoverer.
It may be reproduced with org.eclipse.jdt.core project.

(might be a CDO bug according to André Dietisheim).

We have to switch to EMF Facet before to try to solve such bugs. => P5
