>             Project: Aries
>          Issue Type: Bug
>          Components: Blueprint

> ServiceReferenceRecipe.getService uses a Object.wait to wait for unresolved service references to become available.
> If getService is invoke during a Blueprint container invoked method such as a bean init-method, a bean destroy-method or a bean property setter (etc), this will block the blueprint extender thread. By default it appears that once the three configured blueprint threads are blocked in this way, no more work can be carried out by the blueprint extender (for any blueprint bundle) until the threads unblock (due to the wait timing out or else).
> This was discovered during investigations into ARIES-59. The fix for ARIES-50 will alleviate the problem where optional references are concerned.
