in a class, in the init def, the following line reports an error.
@random_num_obj = Random.new()
NameError: uninitialized constant Random_xy_coords::Random
const_missing at org/jruby/RubyModule.java:2569
initialize at c:/work/source/ruby/rxy.rb:23
(root) at test.rb:4
This code works under ruby.
It seems like jruby doesn't recognize the core object type "Random"
