Monitoring file access of java processes

A mechanism for monitoring file accesses by a process running in a Virtual Machine. File access information associated with a monitored process selected in a first view in a debugging interface is obtained from a file activity log and displayed as selectable file access events in a second view of the debugging interface, wherein each file access event represents a read or write operation performed on a file at a particular point in time by the monitored process. An initial content of a file associated with the selected file access event and revisions made to the file by the monitored process within a defined period of time is retrieved from the file activity log upon detecting user selection of a file access event in the second view. The revisions are applied to the initial content of the file and displayed in a third view in the debugging interface.
