You just need to create a concurrent list of some sort, and when initialValue is called, add the cache to the list before you return it. The threads in bookkeeper live for the lifetime of the process, so you don't need to worry about removing the caches from the list (otherwise a per thread cache would be pointless). ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
