什么是Visual VM中的RMI TCP接受，附加侦听器和信号分配器? [英] What is RMI TCP Accept, Attach Listener, and Signal Dispatcher in Visual VM?

问题描述

我正在使用Visual VM对程序进行性能分析.我的程序运行了一段时间，最后使用显示结果的

如您所愿；Attach，Signal和RMI TCP Accept用于通过jConsole，VisualVM或类似工具进行JMX监视.

其他用于垃圾回收(例如，终结器，引用处理程序).

I'm profiling a program with Visual VM. My program runs for a while and finally pops up a few plots using XChart showing the results. After the charts are displayed, I noticed in Visual VM some active threads "RMI TCP Accept", "Attach Listener", and "Signal Dispatcher". What are these threads? I assume they are there in connection with Visual VM only. Am I correct??

As you assume; Attach, Signal and RMI TCP Accept are for JMX monitoring by jConsole, VisualVM or similar.

The others are for garbage collection (e.g. Finalizer, Reference Handler).
