Re: [jira] [Resolved] (ARIES-896) Deadlock with blueprint services
Posted by Mark Nuttall <mn...@apache.org>.
Hi Guillaume,
We've run into a problem with this change in that unbind-method for
blueprint references no longer work in our environment.
This situation occurs when a bundle providing a service is stopped without
stopping the whole framework. A blueprint <reference> in another bundle has
an unbind-method which should be triggered. As per the OSGi R5 spec section
121.7.10, "The callbacks must be made synchronously with the corresponding
OSGi service event." Aries-896 violates this part of the specification and
results in unbind-methods no longer working correctly.
AbstractServiceReferenceRecipe.serviceChanged() is called because it is a
ServiceListener, and the service is being unregistered. Under Aries-896,
serviceRemoved() is now called under a Runnable(). This is the violation
that I mention above. The effect in our environment is that the bundle
providing the service in question is stopped before serviceRemoved() is
invoked, so that there is no BundleContext associated with the
ServiceReference provided to the blueprint unbind-method. This means that
an unusable ServiceReference is now provided to the unbind-method.
The net result is that application-level unbind-methods are broken in our
environment as a result of the changes to AbstractServiceReferenceRecipe
under Aries-896.
Do you have any suggestions as to how we can restore the broken
unbind-method support without reintroducing the deadlock problems addressed
in Aries-896?
Regards,
Mark
