In passing, the javax.xml.stream changes have really odd formatting, 
some of the sources are a mix of 2 and 4-space indentation.  Also they 
have an really odd "@author Copyright (c) 2009 Oracle Corporation". 
Nothing to do with fixing the doclint warnings but maybe something that 
could be cleaned up when next touching this code.
