Description:
|
1) ArgumentError occurs when I call ActiveRecord::Base.save
2) NoMethodError occurs when I call the has_many asociations.
(using act_as_tree plugin)
These exceptions do not usually occur. These exceptions rarely occurs.
It is not made to reappear in my environment.
If a known problem in JRuby or similar problem, will you teach it?
