> There are simple leaks and one more complex.
> The complex one comes from the fact fact 
> HConnectionManager.HConnectionImplementation keeps a *reference* to the 
> configuration used for the creation. So if this configuration is updated 
> later, the HConnectionKey created initially will differ from the current one. 
> As a consequence, the close() will not find the connection anymore in the 
> list, and the connection won't be deleted.
> I added a warning when a close does not find the connection in the list; but 
> I wonder if we should not copy the HConnectionKey instead of keeping a 
> reference.
