[epsilon-dev] NPE in InMemoryEmfModel

[Maarten Bezemer <maarten.bezemer@xxxxxxxxx>]

Hello,

I stumbled upon an NPE when InMemoryEmfModel is used for resources that are 
not part of a ResourceSet.

The init() method, assumes there is a ResourceSet and uses it to register 
EPackage instances. It is fairly easy to check if there is a ResourceSet 
before registering the packages.

But, this would result in the packages not being registered when there is no 
ResourceSet. I do not know whether this becomes a problem later or not...

So before changing the behaviour of the init() method (and disabling 
registering the packages when there is no ResourceSet), I was wondering about 
your thoughts on this matter.

Cheers,
  Maarten
