Dump/load doesn't work with JRuby 1.6.8

[ytaras]

If I'm trying to load a dump with yaml_db, I see following message:

➜ rake db:data:dump && rake db:data:load --trace
** Invoke db:data:load (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:data:load
rake aborted!

Looks like psych doesn't understand three dots (...) sequence - and I'm not able to switch to sych as it's not supported in JRuby 1.6.8, 1.9 source mode.
