However, that field was only set by the `ClassWriter` and `ClassUseWriter` classes, but never unset by any other writer class, so effectively it contained the *last* instead of the *current* type element. This resulted in summary pages using non-qualified member links, depending on the last previously executing class writer.

Note that this method returns `null` for `ClassUseWriter`, so it changes the generated documentation for class-use pages. The new behavior is preferable, because class-use pages are primarily about other classes using the class, so links to members of the used class should be qualified by the class name. A good example for this are the links to the `FALSE` and `TRUE` fields in the [class use page for java.lang.Boolean][1] which should include the class name.
