[Building Sakai] velocity deadlocks in hashmap

[Joshua Swink]

I'm seeing deadlocks in spite of the upgrade to Velocity 1.6.4:

https://jira.sakaiproject.org/browse/SAK-20389

I'm using Sakai 2.9.2. Could this be due to the fact that earlier versions
of Velocity are used in osp? Here is part of the thread dump:
