[Building Sakai] velocity deadlocks in hashmap

Yea, interesting observation. I didn't know that velocity was upgraded to
avoid this deadlock, that part would have been nice to have in this jar
description.

Frameworks aren't in shared, so it looks like each tool is "really free" to
use whatever version it wants. And some of them are still on old versions.
Actually surprisingly enough half of them, the majority as you noticed
(1.3.1) in osp, but still some 1.6.3 versions in other tools.

In 2.9.3 and trunk the counts are identical these are the counts of each jar

     19 velocity-1.3.1.jar
      1 velocity-1.4.jar
      7 velocity-1.6.3.jar
     26 velocity-1.6.4.jar

find . -name "*velocity-1*.jar" | awk -F/ '{print $NF, $3}' | sort | uniq

velocity-1.3.1.jar osp-common-component
