Denis Golovin commented on JBIDE-18244:
---------------------------------------
I suspect AssertionErrors are result of poor exception handling in freemarker code. Basically it ignores exceptions in various ways and replaces them with null or default values everywhere to go further in code. Then it calls eclipse text framework with what it got. Result is AssertionFiledExceptions without a trace of original problem. I'll push fix for this as part of JBIDE-19740.
