Johann Löfflmann reported the following formatting issues in

http://www-content.oracle.com/technetwork/java/javase/adoptionguide-137484.html

a) missing </u> tag formats all lines after

Hotspot Garbage Collectors

with an underline

b) missing </code> tag formats all lines after

public static final String[] ALLOWED_CLASSNAMES

in both italic and gray color.

both a) and b) makes the 2nd half of the document uncomfortable to read.
