Review Comment:
It appears you're correct that the isMetricCollectionThreadSafe variable
isn't initialized in getKMSMetricsCollector. Since
isMetricCollectionThreadSafe() is a public static method, its behavior now
depends on whether the context is initialized, which introduces a behavioral
change.
At line 186, the code calls isMetricCollectionThreadSafe(), and at line 185,
you're setting the value of the isMetricsCollectionThreadsafe variable, which
is used within isMetricCollectionThreadSafe().
Given that isMetricCollectionThreadSafe() is a public static method, I
recommend initializing the isMetricsCollectionThreadsafe variable during class
loading to ensure consistent behavior in the isMetricCollectionThreadSafe()
method.
