 Near the bottom of the class javadoc for EnumMap, there's a line that's supposed to read

  Map<EnumKey, V> m = Collections.synchronizedMap(new EnumMap(...));

But, because the angle brackets aren't escaped, it comes out as

  Map m = Collections.synchronizedMap(new EnumMap(...));

in the HTML docs. EnumSet has the same problem.
