After renaming an asset and retrieving its older version, both assets (with the old and the new name) appear in the Library. Opening the asset with the older name causes an unexpected error, while opening the asset with the newer name causes the editor not to display the name at all.

NOTE: retrieving the version of an asset before renaming does not change the name of the asset (the asset still has the newest name). Is this a bug, or a feature?

Moreover, renaming a data object and retrieving its older version shows the following message:
Java file could not be parsed, it won’t be possible to open the Editor tab, use the Source tab instead.

See the attached screencast for details.
