| Reading ecore causes stack overflow [message #505657] |

Hi,
I have managed to break EMF, not the best of ways to start the new year ;-(
I have a set of ecore models that all of a sudden started to throw StackOverflowError exceptions when I ran the generator. I figured that the genmodel had become corrupted so I tried to generate a new one. I found out that that also throws a StackOverflowError when reading in the ecore.
While there are five ecore files, I have narrowed it down to a set of two that cause the problem, org.eclipse.ormf.model.base.ecore and org.eclipse.ormf.model.project.ecore; project depends on base.
I very much appreciate ideas on where to start in debugging this.
While these files can be checked out of the ORMF SVN repository, I have tried to make life simple making a zip of these available here ormf.design.model.zip.
Many thanks in advance,
Joel
The exception, note the I have truncated the message to trim the isBounded calls that repeat ad infinitum.
