Generator.new can't handle blocks, and its yield method works incorrectly
-------------------------------------------------------------------------
Key: JRUBY-1643
URL: http://jira.codehaus.org/browse/JRUBY-1643
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.x
Environment: Ubuntu Linux 7.10, JRuby 1.1b1
Reporter: Vladimir Sizikov
Simple example right from ruby-docs:
g = Generator.new { |g|
for i in 'A'..'C'
g.yield i
end
g.yield 'Z'
}
It works under MRI, but fails under JRuby:
Exception in thread "Thread-0" :1: yield called out of block (LocalJumpError)
...internal jruby stack elided...
Even more simple example fails:
g = Generator.new { |ig| ig.yield 888 }
But yield is actually invoked in the block.
Also, calling yield out of block is actually doesn't trigger the error, so it
seems the behavior is exactly an opposite to what is needed.
