When EMF Validation examples are not loaded, the exception occurs. When
EMF Validation examples are loaded, the exception does not occur.
Any idea on the reason for this would be appreciated.
Eclipse Version: 3.3.0 Build id: I20070621-1340
Sun JRE 1.6.02
EMF Validation 1.1.1 200708161445
What I have read so far on ClassCircularityError seems irrelevant (given
the previously mentionned version numbers).

Hi, Loïc,
This is an EMF Validation Framework question, so I have replied to that
newsgroup.
Are you trying to re-use the client-context defined by the example?
This problem has come up a few times before in the EMF newsgroup, so you
might search for possible solutions (or is that what you meant by "what
[you] have read so far?")
One work-around that I recall having some success is to exclude the package
in which the client-context selector is defined from the lazy-start header
in the bundle manifest.
HTH,
Christian
