[news.eclipse.modeling.mdt.uml2] Re: Strategy for loading commercial UML

[Eike Stepper <stepper@xxxxxxxxxx>]

Dawid, Kenn,

And for what I know, NoMagic is currently working on a CDO-based new
version of their team server. Since CDO allows for very scalable EMF
models there will be potential for fewer OutOfMemoryExceptions (although
I'm not sure if your particular OutOfMemoryException is related) ;-)

Cheers
