While the problem is present in commit
https://github.com/mmalmeida/struts-performance/commit/aba93098174c8c8c1684ffdd9bf332b212a893a

The issue was the freemarker version 2.3.9 in that commit.

I tried to remove every unused configuration, file and dependency to
make the project as simple as possible.
