Had a look at the code. Here are some comments (btw, it would be better to create pull requests and discuss code there. This way we get a chance to make changes before they get committed).

• It seems you are ordering imports differently. Might be strict alphabetical. However, we generally sort hibernate imports last (just noticed looking at the diff)
• MetadtaSources looks good
• Nice cleanup in ConfiguredClass#createMappedAttribute. Regarding ConfiguredClass#determineAttributeNature, I probably would have split the method now. It gets a bit too long. One might also consider moving line 603 - 622 last, so that we first check for existing annotations and if there is none we do one final check on whether the referenced type as an annotation.
