class ContentionSnapshot extends AnyRef

A thread contention summary providing a brief overview of threads that are BLOCKED, WAITING, or TIMED_WAITING

While this could be an object, we use instantiation as a signal of intent and enable contention monitoring.

Note

users should ensure that the java.lang.management.ManagementPermission("control") is allowed via the java.lang.SecurityManager.
