Description
While the portions of code written by Sun are indeed under a 3-clause BSD license, the portions written by JJ2000 Partners are not.
The LICENSE.txt file starts with the phrase "Copyright (c) 2005 Sun Microsystems, Inc. All Rights Reserved." which indicates that it is the license for the Sun portion of the code only. In case there are any doubts about this, the COPYRIGHT.txt file contains further Sun copyright information, including the phrase "This distribution may include materials developed by third parties", the implication being that those materials are distributed under separate copyright terms.
Unfortunately the code written by JJ2000 Partners is indeed distributed under different copyright terms, given at the top of each file:
