The threshold value for the collection usage of this memory pool, in bytes. A zero value (0) indicates that no threshold value is configured. When the amount of used memory crosses over this threshold value the JVM will trigger a collection memory threshold exceeded notification, and the jvmMemPoolCollectThreshdCount increases. If collection usage threshold is not supported, then this object, if implemented, will always be equals to 0. In that case, attempting to set this object will trigger an inconsistentValue error. See also jvmMemPoolCollectThreshdSupport. See java.lang.management.MemoryPoolMXBean. getCollectionUsageThreshold(), java.lang.management.MemoryPoolMXBean. setCollectionUsageThreshold(long), java.lang.management.MemoryPoolMXBean. isCollectionUsageThresholdSupported(), java.lang.management.MemoryPoolMXBean. getCollectionUsageThresholdCount()
