If we run "make docs" for src\java.desktop\share\classes\javax\imageio\metadata\doc-files\bmp_metadata.html, javadoc generated is not proper.

Input source html:
</pre>
@since 9
</main>

After make docs:
<dl>
<dt><span class="simpleTagLabel">Since:</span></dt>
<dd>1.5
</main></dd>
</dl>

We should take html file present before JDK-8213050 fix.
