|

* 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
|
||||
* BundleLoader and BundleRepository of the Framework are the primary resources
|
||||
* that are 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. When BundleLoader.findClass() is
|
||||
* called, it results in a lock on the BundleLoader and then a lock on the
|
||||
* BundleRepository. This happens when the DefaultClassLoader loads a class.
|
||||
*
|
||||
* Therefore to avoid this deadlock, if you are going to call
|
||||
* BundleWiring.getClassLoader() you should attempt synchronize against the
|
||||
* BundleLoader and the BundleRepository. 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 BundleLoader or BundleRepository, 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 BundleLoader and the BundleRepository at
|
||||
* the same time and deadlock.
