Concrete implementation of the AbstractMonitoredVm class for the file: protocol for the HotSpot PerfData monitoring implementation.

This class provides the ability to attach to the instrumentation buffer (saved or live) of a target Java Virtual Machine by providing a file URI to a file containing the instrmentation buffer data.
