Setting maximum cache size to 0 ("cache_storage" setting to
""strong:0, soft:0"") should do that effectively (I didn't tried it)
or to plug-in a dummy freemarker.cache.CacheStorage implementation
with the sme setting (use a value like
"com.example.YourDummyCacheStorage").

It has serious performance impact, as without cache getting a template
includes reading it from the HDD (or from the OS disk cache, of
course...) plus parsing the template to Abstract Syntax Tree.

That's a can easily be a critical bug if it's indeed the mistake of
FreeMarker... What FreeMarker version does ${.version} print?
