If you can, create a patch and submit it to Bugzilla.  That way, it
won't get lost in the mix.

hello,

found a problem in MethodLookupUtils when defining a custom function
with no arguments cause the passed parameter array is null in that case.
a simple test for null and providing an empty Class array in this case
solves the issue.
   public static Method lookupStaticMethod(
       Class targetClass,
       String name,
       Object[] parameters)
   {
       boolean tryExact = true;
       Class types[];
       if(parameters==null){
           types = new Class[0];
       }else{
           int count = parameters.length;
           types = new Class[count];
           for (int i = 0; i < count; i++) {
               Object param = parameters[i];
               if (param != null) {
                   types[i] = param.getClass();
               }
               else {
                   types[i] = null;
                   tryExact = false;
               }
           }
       }
   ....
