Missing Javadoc

Hello! I find in your Contributing Guidelines that
All new functionality needs to be documented for users, even if it is very rough for someone to expand on later.

However, I still witness some likely missing Javadoc for public methods in the following files:

• xwiki-platform-core/xwiki-platform-repository/xwiki-platform-repository-server-api/src/main/java/org/xwiki/repository/internal/XWikiRepositoryModel.java
• xwiki-platform-core/xwiki-platform-oldcore/src/main/java/com/xpn/xwiki/XWiki.java
• xwiki-platform-core/xwiki-platform-oldcore/src/main/java/com/xpn/xwiki/objects/classes/BaseClass.java
  ......

Would you like to add Javadoc for these methods or classes, or they are just not that important?
If there is anything I can help with?
