Plus, because there is a single classloader which loads all the classes from a WAR, by keeping the activerReferenceQueue thread alive and holding reference to the queue, we hold reference to its class and the classloader and thus all classes referenced by it.
And this memory leak accumulates with every re-deploy.
Could you interrupt the thread when URLClassLoader#close() is called?
