The alphabetic index in Javadoc is reached by clicking "Index" in
the navigation bar at the top of the page. The second half of the
"P" page in the index:

http://java.sun.com/j2se/1.5.0/docs/api/index-files/index-16.html
 
is truncated in Internet Explorer due to an HTML error -- the
parameter <Object> is output with angle brackets rather than the &lt; and &gt; entities, as shown here, and so is mistakenly interpreted as the <Object> tag
rather than the string:

<DT><A HREF="../java/awt/image/renderable/ParameterBlock.html#ParameterBlock(java.util.Vector)"><B>ParameterBlock(Vector<Object>)</B></A>
