> When a {{KMSClientProvider}} is initialized in _ssl_ mode, It  initializes a {{SSLFactory}}
object. This in-turn creates an instance of {{ReloadingX509TrustManager}} which, on initialization,
starts a trust store reloader thread.
> It is noticed that over time, as a number of short lived {{KMSClientProvider}} instances
are created and destroyed, the trust store manager threads are not interrupted/killed and
remain in TIMED_WAITING state. A Thread dump shows multiple:
