Description Cedric Brun

1. create a new class diagram
2. click on "nodes"=>"Class" and create a class
3. click on "edges"=>"Containment link" and click on the previously created class

Eclipse become unusable, errors are poping up on every action and the error log is filled with Exceptions caused by :

Caused by: java.lang.IllegalStateException: There is a cycle in the containment hierarchy of org.eclipse.uml2.uml.internal.impl.ClassImpl@1cc858 (name: Class0, visibility: <unset>) (isLeaf: false, isAbstract: false) (isActive: false)
at org.eclipse.emf.ecore.util.EcoreUtil.getRootContainer(EcoreUtil.java:811)
at org.eclipse.uml2.common.util.CacheAdapter.addAdapter(CacheAdapter.java:282)
at org.eclipse.uml2.common.util.CacheAdapter.getNonNavigableInverseReferences(CacheAdapter.java:298)
at org.eclipse.uml2.common.util.UML2Util.getNonNavigableInverseReferences(UML2Util.java:1104)

Looks like after this sequence of actions the model is cycling in its containment structure.

Containment link must have different element ends

If A contains B, ContainmentLink creation from B to A does not modify containment (the result should be B contains A after ContainmentLink creation).

Several bug are open related to the ContainmentLink behavior -> see Bug318000
