RFR: 8374038: JDI EventRequestManager javadoc has unrendered @link tags inside an @code block

[Chris Plummer]

Get rid of @link blocks embedded inside @code block since they are not rendered. I searched the rendered JDI javadoc for additional @link references showing up as raw text and didn't find any.
