Apache Axis2 was recently updated to depend on backport-util-concurrent 
3.1 instead of 2.2.   Axis2 distributes a copy of a backport license 
like this:    

Looks like its outdated.  I looked at the backport 3.1 code and README 
and it seems that the attribution to Sun for the CopyOnWriteArrayList 
hasn't been needed since 2.0_01?

Could someone recommend the best way to update the axis2 license for 
I see some relevant info in 3 files: LEGAL, README.html (License 
section) and LICENSE.html.
It's kinda confusing to have the legal and license info in 3 files.
Maybe it's best that in axis2 we combine them like this:

backport-util-concurrent is based in large part on the public
domain sources from:
   1) JSR166,
   2) package dl.util.concurrent,
   3) Doug Lea's "collections" package.

Does this make sense?
