Re: [Freemarker-devel] Object lock in freemarker

[Attila S. <sze...@gm...>]

Does your dump show another thread holding the lock?

Also, note this list is retired (I’m surprised I still get mail from it, especially since I no longer am active in the project…) See <http://freemarker.org/mailing-lists.html <http://freemarker.org/mailing-lists.html>> for the current lists, or any of the other options in the “Community” sidebar on the website.
