>
> In the constructor of {{SpillableMemoryManager}}, a {{NotificationListener}} is added to the {{MemoryMXBean}}. This listener is never removed, even if the application is re-deployed.
> This results in the instance {{SpillableMemoryManager}} being still reachable after a redeploy. This results in its class being reachable, which results in the classloader being reachable, along with all the classes in it.
> This leads to metaspace OutOfMemoryErrors.
