A sample project demonstrating this issue.

Create a transformation that creates a UML model. Add reference to another model, e.g. PackageImport of UML Primitive Types library. "java.lang.OutOfMemoryError: Java heap space" will occur after some 100 iterations.

The problem is that UML2Writer doesn't unload the resources after saving them in a file. That's why CacheAdapter.InverseCrossReferencer keeps the objects that are not in use any longer.
