[news.eclipse.modeling.gmf] Error on RCP product export, when OCL valida

[Marco Stein <Marco_Stein@xxxxxxx>]

Hi there,

i have just downloaded and installed GMF2.2.0RC4 and all build 
dependencies and suppose to have a clean installation.

My diagram modeler works wonderfully. Big thanks to the GMF people :-)
I am also able to export the RCP diagram modeler as a product.

Now that the diagram modeler works fine, I want to add constraints using 
OCL. I add the constraints to the gmfmap model, recreate the 
gmfgen-model (all OK) , and set the gmfgen-models properties for 
validation support:
Live Validation UI Feedback		true
Validation Decorators			true
Validation Enabled			true
Validation Decorator Provider Priority	Medium

After recreation of the diagram editor, it works fine when run as 
eclipse application. Validation works fine as expected.

But now the addition of OCL has broken my ProductExport, which quits 
with the attached message. There is some error with the
net.sourceforge.lpg.lpgjavaruntime

What could be the possible cause of this problem? Any hints?

best regards,
Marco Stein
