如何正确ping JGroups

Question

我有一个基于jgroup的应用程序，并使用netcat检查应用程序是否已启动并运行(在马拉松中进行健康检查，管理应用程序的启动顺序)：

nc -z -w 1 app 7801

除了jgroup日志之外，一切都很好，但有以下例外：

WARN  org.jgroups.protocols.TCP - JGRP000006: failed accepting connection from peer
app        | java.io.EOFException: null
app        |        at java.io.DataInputStream.readFully(DataInputStream.java:197)
app        |        at org.jgroups.blocks.TCPConnectionMap$TCPConnection.readPeerAddress(TCPConnectionMap.java:511)
app        |        at org.jgroups.blocks.TCPConnectionMap$TCPConnection.<init>(TCPConnectionMap.java:381)
app        |        at org.jgroups.blocks.TCPConnectionMap$Acceptor.handleAccept(TCPConnectionMap.java:303)
app        |        at org.jgroups.blocks.TCPConnectionMap$Acceptor.run(TCPConnectionMap.java:287)
app        |        at java.lang.Thread.run(Thread.java:745)

有没有一种更合适的方式来"ping“一个jgroup应用程序？
