Error loading representations file in Mars (regression?) [message #1697255]

I have a model whose representation's file opens in Luna SR2 (4.4.2) but fails to open in Mars (4.5 RC1) with the exception below.

The core of the error is the following:

org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: org.eclipse.emf.ecore.xmi.IllegalValueException: Value 'org.eclipse.emf.ecore.impl.EPackageImpl@6040c56c (eProxyURI: platform:/resource/org.eclipse.papyrusrt.xtumlrt.common.model/model/common.ecore#/)' is not legal. (platform:/resource/org.eclipse.papyrusrt.xtumlrt.common.model/model/representations.aird, 3, 60)

This is very strange because it suggests that a URI value is not legal, namely the URI of the corresponding .ecore file, but that value, in particular that file is legal, and it is there, next to the representations file.

What's the problem?

Is this a regression?

The error occurs in

Eclipse Modeling Tools 4.5.0.20150520-1810 epp.package.modeling null

which comes with

Hi,

the .aird file should be migrated during the loading, but if you at some point you did test milestone builds of EcoreTools and Sirius you could end up with a migration which is not trigerred.
At the top of the .aird file there is version attribute in the viewpoint:DAnalysis root, can you paste here its value ? (something like : version="10.0.10.201502231700")

The value is

version=10.0.10.201502231700

The file still doesn't open with

Eclipse SDK 4.5.0.I20150603-2000
Ecore Diagram Editor (SDK) 3.0.0.201505261431

Is there any way I can trigger the migration manually?

Thanks

yes, replace the version with an older one in the .aird file like version="8.1.1", then during loading the migrations in between will be triggered.
