merlimat opened a new pull request #1274: Ensure we instantiate threads that extend Netty FastThreadLocalThread
URL: https://github.com/apache/bookkeeper/pull/1274
 
 
   Since we make heavy use of `Recycler` and other `FastThreadLocal` objects from Netty, we should make sure that all (critical) threads that we instantiate are inheriting from `FastThreadLocalThread`.
   
   `FastThreadLocalThread` has an optimization that makes access to `FastThreadLocal` faster. It's a class that extends regular `Thread` and adds a field for the thread local access.
   
   There are a couple of places where we're currently not using `FastThreadLocal`: 
    * `OrderedScheduler` builder
    * `BookieThread` (which is used in `Journal`, `ForceSyncThread`, etc..)
