Description Simon Goodall

Build Identifier: 20100218-1602

I have generated an Epatch from a ResourceSet containing two different model based on different underlying ecore models.

When trying to apply the patch using the CopyingEpatchApplier class I get an IllegalArgumentException claiming my feature is not found.

This is caused by the CopyingEpatchApplier.matchResource(NamedResource,Resource) method trying to find a matching resource for the object. It results in trying to find the object with a feature from ecore model A in ecore model B which of course results in it unable to find the feature. Unfortunately this issue is not caught leading to the patch process to abort.

Reproducible: Always

Steps to Reproduce:
1. Create two different ecore models
2. Create an instance of each of the ecore models
3. Load both into a single ResourceSet
4. Create a EpatchRecorder with the resource set
5. Make some changes to the models
6. Generate the patch from the recorder
7. Create an instance of CopyingEpatchApplier, passing in patch, resourceset and Right_to_left mode
8. IllegalArgumentException is thrown.

EPatch was a contribution from an external contributor which stopped
maintaining its work. It is now deprecated in favor of the MPatch plugins.
