Element VAR is undefined in ATTRIBUTES ColdFusion 11

I am trying to call a method from a java class but I am getting an exception I haven't seen before.

This is what I get back when I am calling the class and one of the methods and how I got this

<cfdump var="#nlp#">
<cfdump var="#nlp.run()#">

enter image description here

And this is the exception I got when I am trying to dump the method

19:12:31.031 - Expression Exception - in Z:/Sites/xamplifier/views/surveyreporting/wordcloud.cfm : line 157
        Element VAR is undefined in ATTRIBUTES.

Am I calling the method in a wrong way? This is how we had the code on CF9 and everything works but CF 11 seems to have issues...

It looks like the Open_NPL run() method is generating an exception, which is caught and causes it to return null. See here: Open_NPS Source

Agree with the other answers, you'll just have to test for NULL to avoid the CF exception, and dig into the Java to determine the root cause.

The Java method is returning NULL, which in ColdFusion is the same as not being defined. You need to capture the result and test it.

<cfset local = {}><!--- if inside a function, this isn't necessary --->
<cfset local.result = nlp.run() >
<cfif not isNull( local.result ) >
  <cfdump var="local.result">
<cfelse>
  NULL!
</cfif>
