I can see the *ASTFunctionNode *class file in the *org.apache.commons.jexl3.parser* package of the *commons-jexl3-3.2.1.jar* file.
Can you provide more details? - what specific version of jexl are you using? - can you provide the fully qualified name of the *ASTFunctionNode *class file that you're missing (i.e. including the package name) - can you provide the full class path for your application? - can you provide any stack trace for where its failing with the missing class?
