------------------------------------

The 2.0.1 library is realy outdated now. Please try to use 2.1.1 library to see your problem is resolved in it.

> I used the jexl-2.0.1 in my project for process the user request data.Recently i met a problem,the jexl expression does not work correct. So i kill the preocess and restart my application.it work good!
> I seems like the *JexlEngine.createExpression(String exp)* goes in wrong way,It create a Expression object which has a *simpleNode* in it.So when the Excepssion oject call method *evaluate(JexlContext)* thow a *UnsupportedOperationException:Not Supported yet (Interpreter.java line 1338).*
> Expression in my project is *ASTReference*,it looks like this *"ff:upper('sss')"*
