I was unable to reproduce this on master or jruby-1_6 branches using the following command line. Something specific to running in the console, maybe?

$ jruby --1.9 -e "require 'config/application'; str = ERB.new(File.read(::Devise.ldap_config || \"#{Rails.root}/config/ldap.yml\")).result; Thread.abort_on_exception = true; (1..100).map{Thread.new{loop {p YAML.load(str)}}}.map(&:join)"

I think your example moves the File.read and ERB.new outside the threads. The thread test was limited to YAML.load

My test was to reproduce what happens intermittently as the web app runs. Literally to take a line of code from the devise_ldap_authenticatable gem and run it within the threads.

I'm unclear if this is a coding problem or a jruby problem. Working with the ldap gem guys,it appears to work with MRI. It seems right now as if the problem is with ERB.new()?

Confirmed with ldap_authenticatable team that the problem is within ERB.new or ERB.new().result.

Let's be optimistic and say this is fixed.

Since this bug was filed, we've fixed literally dozens of encoding issues, including many that would trigger IndexOutOfBounds.

If you can reproduce it, please reopen
