Description

[na:1.8.0_111] Caused by: java.lang.UnsupportedOperationException: Usage threshold is not supported at sun.management.MemoryPoolImpl.setUsageThreshold(MemoryPoolImpl.java:114) ~[na:1.8.0_111] at org.apache.nifi.controller.MonitorMemory.onConfigured(MonitorMemory.java:178) ~[na:na] ... 16 common frames omitted

MonitoryMemory checks if memoryPoolBean.isCollectionUsageThresholdSupported()) and if so it eventually calls monitoredBean.setUsageThreshold(calculatedThreshold), but setUsageThreshold then checks isUsageThresholdSupported() so it can throw UnsupportedOperationException.
