Description Stéphane Thibaudeau CLA 2012-01-25 12:00:45 EST 
Build Identifier: 1.1.2.v20110202-0936

I provide my own action with the org.eclipse.emf.compare.ui.export extension point.
Now when I compare 2 models and select the "complete resourceset(s)" option I get a NullPointerException.

The problem is that my models reference another model using a pathmap URI.
This URI has no file extension.
Then EMF Compare picks the file extensions which are both null and tries to compare them using leftExtension.equals(righExtension) =>  NPE

Reproducible: Always

Steps to Reproduce:
Compare models who have no file extension
