Description

If you pass a Ruby Array to a java method that expects a Java primitive array it should be automatic.

Also in this vein We need a nicer syntax for making Arrays from Java The following is not so nice:

arr = JObject[].new(2)
arr[0] = 1
arr[1] = 2

Fixing subject; this bug should be used to make easier syntax for both object and primitive arrays.

Note the only way I could find to create and manipulate primitive arrays is as follows:

irb(main):047:0> my_array = Java::JavaClass.for_name("int").new_array(3)
=> [I@8eb7e0
irb(main):048:0> my_array[0] = java.lang.Integer.new(100).java_object
=> 100

Yuck. And it's not smart about unwrapping Ruby values to stuff in the array either.
