Plugins should do any global actions in a separate method called by the agent from a single thread.

Weird, but common in debugging JVM? OS?
Hope you can remove that "sleep 1" line.

I even tried reproducing on JRuby 1.6.3 (the version released with logstash 1.0.17 which had this problem) and I couldn't reproduce it. So strange!
The tickets linked in this issue show me easily able to reproduce this. I tested on 1.6.3, 1.6.5, and 1.6.7 - no problems, crazy! I'll try again today

autoload should have no relation to this issue as I wrote above. What is suspected is the multi-threading require problem.

Thanks. Cannot reproduce with JRuby 1.6.6+? We backported thread-safe autoload and a possible multi-threading require problem at 1.6.6 so it might affect this issue...

Plugins currently are supposed to load ruby libraries in the 'register' method, but in inputs and filters this could be invoked simultaneously in separate threads.
Split 'register' into two methods. global_init and instance_init, perhaps with better names. Alternately, if 'register' is really for global only things, then just move where 'register' is called and update the docs describing its intent.
