Provides the implementation classes for the rmi: protocol for the HotSpot PerfData instrumentation buffer monitoring implementation.

The rmi: protocol is the default protocol for the PerfData implementation when a hostname is specified as part of a HostIdentifier or VMIdentifier. It communicates with an RMI server on the remote machine that provides functions to get a list of available Java Virtual Machines and to acquire a copy of a Java Virtual Machine's instrumentation buffer. The RMI server may or may not use the PerfData implementation on the remote host to acquire this information. The jstatd server provides a PerfData implementation of the RMI server.
