Description

Hi!

In a clean ruboto-core project, try

require 'yaml'

I get the output below. I see references to yecht.jar in yaml/yecht.rb and in Ruby.java And what is YechtService? Please help! I need to get yaml, activerecord, and derby working this week

See ~~JRUBY-5567~~ for the root cause of this, and ~~JRUBY-5566~~ for the eventual "proper" fix.

The root cause of this issue was ~~JRUBY-5567~~, for which I've made a preliminary fix. We'll call this one fixed, since ~~JRUBY-5567~~ remains open and I'll come up with a more robust answer for JRuby 1.6.1.

With the preliminary fix in place, YAML successfully loads from a ruboto-core app.

Preliminary fix for ~~JRUBY-5567~~: Invokers will fail to generate and kill method binding on systems that do not support bytecode loading

I added logic into MethodFactory to attempt to load a class, forcing reflected invokers forever if this fails in any way. I have confirmed manually that this does not interfere with normal execution, and have left logging in place that indicates when it has fallen back. See ~~JRUBY-5568~~ for a task to remove this logging before JRuby 1.6 final.

~~JRUBY-5567~~ will remain open until a more robust solution can be found (JRuby 1.6.1).

See also ~~JRUBY-5566~~, which this issue caused.

Thank you so much for fixing this!

We are now loading ActiveSupport and ActiveRecord OK!
