Daniel Dekany commented on FREEMARKER-29:
-----------------------------------------
Also note this possibly related version history change in 2.3.23:
{quote}
Bug fixed: If a template "file" was successfully opened for reading, but then
there was an IOException during reading its content, the parser (JavaCC) acted
like if the template "file" was ended there, and the exception was suppressed.
It's actually a JavaCC quirk that affects many other JavaCC-based languages
too, but now FreeMarker has added a workaround in the Template constructor, and
so now an exception will be thrown as expected.

That is, perhaps the exception has occurred earlier too, but it has silently
chopped the template. Though it's strange that it instead of any "real"
{{IOException}} it dies in the {{BufferedReader}} due to closed reader...
