Primitive array in functions declaration throws exception

When the drl file contains the declaration of a function having a primitive array as parameter, the compiler complains it is unable to find the class for this primitive array. This is the case for primitive arrays containing primitive types or objects. Example is attached. I also attached a patch.

There is a drawback in this patch, I don't know how to fix this another way. Currently, if the user define a function having an array of java object as argument, the type must be fully qualified.
