        * javax/swing/text/html/StyleSheet.java:
        Add generic typing.

changed the code to do ArrayList.set() on an instance thats allocated like this:

    List<Map<String,String>> attributes =
      new ArrayList<Map<String,String>>(count);

This is, however, broken as ArrayList constructor only ensures capacity but
doesn't allow you to set() elements outside of ArrayList.size(). This causes
the following exception to happen upon JPC start-up:

Fix that up.
