> As described in https://issues.apache.org/jira/browse/GERONIMO-5554 there is potential deadlock in the Blueprint service code.
> In particular, ServiceRecipe has a lock hierarchy of getting an instance lock on the ServiceRecipe instance and then getting the Blueprint container-wide lock for the blueprint repository. However, while the blueprint container is creating its instances a thread may also come into the ServiceRecipe lookup code already having the blueprint repository lock.
> In such a case deadlock is possible because two threads can attempt to obtain the lock in either order.
