> The MonitorMemory reporting task is intended to report when heap is becoming 
> exhausted by comparing the amount of heap used immediately after the most 
> recent garbage collection to the configured threshold. It appears that this 
> was broken in NIFI-1690, in which the code was changed to use 
> {{MemoryPoolMXBean.getUsage()}} instead of 
> {{MemoryPoolMXBean.getCollectionUsage()}}
