If you talk to them, please tell them that I think I found the reason
for most of the errors:

The following code does not behave consistently with C Ruby in JRuby trunk/HEAD:
Kernel.raise "Hello" # => NoMethodError: private method 'raise' called
for Kernel:Module
In Ruby it raises RuntimeError: Lala

(I was unable to subscribe to dev at jruby.codehaus.org)
