/**
|
||||
* Utility class to get the BundleRepository object associated with a Bundle, to
|
||||
* potentially synchronize against that object.
|
||||
*
|
||||
* Specifically if a call to BundleWiring.getClassLoader() is invoked on a
|
||||
* thread other than main/UI thread, then there is a possible deadlock if the
|
||||
* application shuts down while the BundleWiring.getClassLoader() call is still
|
||||
* going. The BundleRepository of the Framework is the primary resource that is
|
||||
* in contention in this deadlock scenario, due to the BundleRepository being
|
||||
* used as a synchronization lock both deep in bundleWiring.getClassloader() and
|
||||
* in Framework shutdown code. The other resource used as a synchronization lock
|
||||
* and causing the deadlock is the BundleLoader associated with the bundle.
|
||||
*
|
||||
* Therefore to avoid this deadlock, if you are going to call
|
||||
* BundleWiring.getClassLoader() you should attempt to get the BundleRepository
|
||||
* and synchronize against it. This will ensure the call to getClassLoader() can
|
||||
* finish and then release synchronization locks of both the BundleRepository
|
||||
* and BundleLoader.
|
||||
*
|
||||
* If we fail to get the BundleRepository due to access restrictions, then you
|
||||
* should proceed onwards anyway because the odds of the application shutting
|
||||
* down at the same time as the call to BundleWiring.getClassLoader() is still
|
||||
* running is low. Even if that occurs, the odds are further reduced that the
|
||||
* two threads will synchronize against the BundleRepository at the same time
|
||||
* and deadlock.
