Hi doclet maintainers,

This is a bug report with what might be an easy fix.

At javadoc8's suggestion, jsr166 javadoc tables now have <caption> tags.
But the caption text is invisible, because the background color is the same as the foreground color, #FFFFFF.

See the invisible text for yourself here:
http://gee.cs.oswego.edu/dl/jsr166/dist/docs/java/util/Deque.html
If you mouse-select the caption text, it magically becomes visible.

I think the culprit is this code from
src/share/classes/com/sun/tools/doclets/internal/toolkit/resources/stylesheet.css

.overviewSummary caption, .packageSummary caption, .contentContainer ul.blockList li.blockList caption, .summary caption, .classUseContainer caption, .constantValuesContainer caption {
    position:relative;
    text-align:left;
    background-repeat:no-repeat;
    color:#FFFFFF;
    font-weight:bold;
    clear:none;
    overflow:hidden;
    padding:0px;
    margin:0px;
}

I have reason to believe that if you change the color: above to e.g. color:#353833, the captions will become visible. I have no idea whether anything else will change.
