[logback-user] Missing classfile with Filter Evaluator

[George, Kenneth V [NTK]]

I am creating a filter for one of the appenders and I am getting this error:

Exception in thread "main" java.lang.NoClassDefFoundError: org/codehaus/janino/ScriptEvaluator

I have attempted to look around and cannot find the class anywhere in the .jar files shipped with the product.

Anyone know where it is?
