RFR: 8335397: Improve reliability of TestRecursiveMonitorChurn.java

Mon Jul 1 09:27:50 UTC 2024

TestRecursiveMonitorChurn.java currently uses NMT to try and correlate the native memory increase with unwanted inflation.

Change to instead query the JVM for exact number of inflations via the Whitebox API. This allow us to both be more exact and less dependent on interactions with NMT.
