[Fedora-packaging] license for concurrent package

[Permaine Cheung]

Hi,

The concurrent package in core has stated the following (under the Notes 
section of its URL
http://gee.cs.oswego.edu/dl/classes/EDU/oswego/cs/dl/util/concurrent/intro.html): 


'All classes are released to the public domain and may be used for any 
purpose whatsoever without permission or acknowledgment. Portions of the 
CopyOnWriteArrayList and ConcurrentReaderHashMap classes are adapted 
from Sun JDK source code. These are copyright of Sun Microsystems, Inc, 
and are used with their kind permission,' (link is 
http://gee.cs.oswego.edu/dl/classes/EDU/oswego/cs/dl/util/sun-u.c.license.pdf) 

And further down from that page it states:
'Do I need a license to use it? Can I get one? No!'

Is this okay?

Thanks,
Permaine
