Re: Object lock in freemarker

Especially since this list is retired, see my comment on SO:
http://stackoverflow.com/questions/38691722/object-block-in-freemaker

If you can reproduce this deadlock reliably, upgrade to the latest
stable release (2.3.25-incubating ATM), and see if it goes away.
(Indeed, you should upgrade no mater what... 2.3.13 is from 2008.)
