Given a class:
public class Foo
private class Bar
FindBugs (which I believe uses the JXR generated files) lists problems in inner classes as being on line zero. The zero is a link, which points to something like http://SITE_URL/SITE_DIRECTORY/xref/com/blah/blahblah/Foo$Bar.html#0. However, there is no Foo$Bar.html file; only Foo.html. Inside Foo.html, there doesn't seem to be any anchors denoting the inner class.
...or is this a FindBugs issue???
