这样大家看的出是云里雾里. 回复4: Local Applications Cannot Be Detected (Error Dialog On Startup) Description: An error dialog saying that local applications cannot be detected is shown immediately after VisualVM startup.
Resolution: This can happen on Windows systems, it's a known problem related to the jps JDK tool used by VisualVM to detect running Java applications. There are two main root causes: broken access rights to temporary directory on a NTFS disk - see this thread for details and fix or having temporary directory on a FAT disk - see this bug detail for details and fix.
