Undefined method exclusive for Thread class
-------------------------------------------
Key: JRUBY-4154
URL: http://jira.codehaus.org/browse/JRUBY-4154
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.4.0RC2
Environment: osx
Reporter: McClain Looney
While writing some middleware, installing Rack::Reloader will break the
application thusly:
The relevant code in reloader (line 35 is the call to Thread.exclusive()):
def call(env)
if @cooldown and Time.now > @last + @cooldown
if Thread.list.size > 1
Thread.exclusive{ reload! }
else
reload!
end
@last = Time.now
end
@app.call(env)
end
