Uwe Schindler created LUCENE-7726:
-------------------------------------

             Summary: Fix Javadocs HTML entity bugs
                 Key: LUCENE-7726

          Components: general/javadocs

As of jdk9-ea-b158, {{ant documentation}} seems to build the core javadocs just fine, but fails on the  {{lucene/memory/}} javadocs...

looking at the generated html files turns up this...

The source java file has this...

 * <a target="_blank" href="http://www.acmqueue.org/modules.php?name=Content&pa=showpage&pid=293&page=4">
 * A Call to Arms - Custom subscriptions</a>, and Tim Bray's
{noformat}

...which does in fact seem to be invalid HTML ... aren't {{&}} always suppose to be encoded as {{&amp;}} ... even in URLs?

I'm suprised the java8 javadocs/linter don't warn about this.
