LoadingMessageSourceProvider can cause OOM errors #1
Description
LoadingMessageSourceProvider creates a thread factory which creates daemon threads with no way of shutting them down.
The comments explicitly states:
/*
* Use daemon threads. We don't give control to the user about the
* ExecutorService, and we don't have a reliable way to shut it down (a JVM
* shutdown hook does not get involved on a webapp shutdown, so we cannot
* use that...).
*/
Unfortunately, this can cause OutOfMemory errors, especially in an OSGi environment, when these threads stay alive across bundle restarts. This provider should expose a way to safely shutdown / manage the lifecycle of the executor service threads.
Also, json-schema-validator which consumes this library should also expose a way to shut this down.
