@valych: You don't add the Integer.class at the end for the length, this is just a Pawn thing because the length of the array is not known when you pass it to the plugin. Your function should look like this:

PHP код:

instance.registerFunction("java_TestArray", objects -> { 
            int someValue = (Integer) objects[0]; // in this line the java.lang.ClassCastException is being thrown (read below) 
            Integer[] array = (Integer[])objects[1]; 
            for (int i = 0; i < array.length; i++) { 
                if(someValue == 33) { 
                    array[i] = (i + 2) * 4; 
                } else { 
                    array[i] = i+1; 
                } 
            } 
            return 1; 
        }, Integer.class, Integer[].class); 


The rest should be alright.
