In https://hk2.java.net/2.2.0-b24/api-overview.html search for "filer" and replace it with "filter".
A little bit down the page "ActiveDescriptor<?>" is rendered as a hyperlink, but:
- It's not clickable (the text is blue, but not a real hyperlink).
- The closing '>' is not part of the hyperlink.
A little bit down the page, find "managaging" and replace it with "managing".
