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

It has turned out that the problem is reproduced if I try to initialize JEXLEngine with functions without a namespace in a way like this

{code}

    functions = new HashMap<String, Object>();
    // Register default function namespaces
    functions.put(null, new DefaultFunctions(this));
...

    // Jexl Setup

    boolean verboseScripting = true;
    boolean strict = false;

    JexlBuilder jb = new JexlBuilder();
    jb.silent(!verboseScripting);
    jb.strict(strict);
    jb.namespaces(functions);
...
{code}

To be sure, the class DefaultFunctions does not contain method z. If I comment out the line  {code} // functions.put(null, new DefaultFunctions(this)); {code} everything works as expected. Now I wonder if it's correct to register functions with null namespace ?
