Comment 1 William Piers CLA 2011-08-04 04:34:30 EDT 
Clarifying a bit: to obtain the previous error I was launching the runtime with the registryMultiLanguage option, because the real error was the following:


!ENTRY org.eclipse.equinox.registry 4 0 2011-08-04 10:28:30.952

Comment 2 Laurent Goubet CLA 2011-08-04 04:45:34 EDT 
This has already been fixed on both master and 1.2. This was a problem with the 1.2.0, please use one of the nightlies that have been published since then. (see http://www.eclipse.org/modeling/emf/downloads/?project=compare for the list of 1.2.0 nightlies, or use the update site http://download.eclipse.org/modeling/emf/compare/updates/nightly/1.2/ .
Comment 3 Laurent Goubet CLA 2011-08-04 04:58:14 EDT 
Was not "invalid" ... but "fixed"
