          Components: freemarker
         Environment: Eclipse 4.4.1
Linux
            Reporter: Eric Sirianni


I get constant "assertion failed" errors in the freemarker editor.  The error is associated with the following stack trace in my eclipse log:

This happens across multiple FreeMarker templates, all with very basic syntax.

I am using version 1.4.1.Final of the FreeMarker plugin.
