/**
* This package provides classes to create events and control Flight Recorder.
* 
* Defining events
* 
* Flight Recorder collects data as events. An event has a time stamp, duration
* and usually an application-specific payload, useful for diagnosing the
* running application up to the failure or crash.
* 
* To define a Flight Recorder event, extend {@link jdk.jfr.Event} and add
* fields that matches the data types of the payload. Metadata about fields,
* such as labels, descriptions and units, can be added by using the annotations
* available in the {@code jdk.jfr} package, or by using a user-defined
* annotation that has the {@link jdk.jfr.MetadataDefinition} annotation.
* 
* After an event class is defined, instances can be created (event objects).
* Data is stored in the event by assigning data to fields. Event timing can be
* explicitly controlled by using the {@code begin} and {@code end} methods
* available in the {@code Event} class.
* 
* Gathering data to store in an event can be expensive. The
* {@link jdk.jfr.Event#shouldCommit()} method can be used to verify whether
* an event instance would actually be written to the system when
* the {@link jdk.jfr.Event#commit()} method is invoked.
* If {@link jdk.jfr.Event#shouldCommit()} returns {@code false},
* then those operations can be avoided.
* 
* Sometimes the field layout of an event is not known at compile time. In that
* case, an event can be dynamically defined. However, dynamic events might not
* have the same level of performance as statically defined ones and tools might
* not be able to identify and visualize the data without knowing the layout.
* 
* To dynamically define an event, use the {@link jdk.jfr.EventFactory} class
* and define fields by using the {@link jdk.jfr.ValueDescriptor} class, and
* define annotations by using the {@link jdk.jfr.AnnotationElement} class. Use
* the factory to allocate an event and the
* {@link jdk.jfr.Event#set(int, Object)} method to populate it.
* 
* Controlling Flight Recorder
* 
* Flight Recorder can be controlled locally by using the {@code jcmd}
* command line tool or remotely by using the {@code FlightRecorderMXBean}
* interface, registered in the platform MBeanServer. When direct programmatic
* access is needed, a Flight Recorder instance can be obtained by invoking
* {@link jdk.jfr.FlightRecorder#getFlightRecorder()} and a recording created by
* using {@link jdk.jfr.Recording} class, from which the amount of data to
* record is configured.
* 
* Settings and configuration
* 
* A setting consists of a name/value pair, where name specifies the
* event and setting to configure, and the value specifies what to set
* it to.
* 
* The name can be formed in the following ways:
* 
* {@code
* <event-name> + "#" + <setting-name>
* }
* 
* or
* 
* {@code
* <event-id> + "#" + <setting-name>
* }
* 
* For example, to set the sample interval of the CPU Load event to once every
* second, use the name {@code "jdk.CPULoad#period"} and the value
* {@code "1 s"}. If multiple events use the same name, for example if an event
* class is loaded in multiple class loaders, and differentiation is needed
* between them, then the name is {@code "56#period"}. The ID for an event is
* obtained by invoking {@link jdk.jfr.EventType#getId()} method and is valid
* for the Java Virtual Machine instance that the event is registered in.
* 
* A list of available event names is retrieved by invoking
* {@link jdk.jfr.FlightRecorder#getEventTypes()} and
* {@link jdk.jfr.EventType#getName()}. A list of available settings for an
* event type is obtained by invoking
* {@link jdk.jfr.EventType#getSettingDescriptors()} and
* {@link jdk.jfr.ValueDescriptor#getName()}.
* 
* Predefined settings

* </table>
* 
* Null-handling
* 
* All methods define whether they accept or return {@code null} in the Javadoc.
* Typically this is expressed as {@code "not null"}. If a {@code null}
* parameter is used where it is not allowed, a
* {@code java.lang.NullPointerException} is thrown. If a {@code null}
* parameters is passed to a method that throws other exceptions, such as
* {@code java.io.IOException}, the {@code java.lang.NullPointerException} takes
* precedence, unless the Javadoc for the method explicitly states how
* {@code null} is handled, i.e. by throwing
* {@code java.lang.IllegalArgumentException}.
