Hello Franciso,
I did this little experiment :
---8<---
require 'rubygems'
require 'json'
puts `ruby -v`
puts `gem search json`
h = {}
p = h
(1..21).each do |i|
p['a'] = {}
p = p['a']
end
s = h.to_json
p s
h = JSON.parse(s)
p h
--->8---
Here are the results :
---8<---
jruby 1.4.0 (ruby 1.8.7 patchlevel 174) (2009-11-02 69fbfa3) (Java
HotSpot(TM) 64-Bit Server VM 1.6.0_17) [x86_64-java]
json-jruby (1.2.0)
"{\"a\":{\"a\":{\"a\":{\"a\":{\"a\":{\"a\":{\"a\":{\"a\":{\"a\":{\"a\":{\"a\":{\"a\":{\"a\":{\"a\":{\"a\":{\"a\":{\"a\":{\"a\":{\"a\":{\"a\":{\"a\":{}}}}}}}}}}}}}}}}}}}}}}"
t.rb:19: nesting of 20 is too deep (JSON::NestingError)

I'm afraid I can't help with that one. The json-jruby thing seems to
be a faithful port to jruby, even when it comes to limitations.
I've googled a bit :

http://github.com/brianmario/yajl-ruby/tree/ffi
The FFI branch is in pause since november :(

Refactoring for the win.
