[jboss-jira] [JBoss JIRA] Commented: (JGRP-1263) org.jgroups.protocols.UDP - failed sending message to null

org.jgroups.protocols.UDP - failed sending message to null ---------------------------------------------------------- Key: JGRP-1263 URL: https://issues.jboss.org/browse/JGRP-1263 Project: JGroups Issue Type: Bug Affects Versions: 2.10 Environment: Linux, Java 1.6.18 32bit Reporter: Adrian Tarau Assignee: Bela Ban This occurs random and affect the notification mechanism built in our application. Looking in TP // Don't send if destination is local address. Instead, switch dst and src and send it up the stack. // If multicast message, loopback a copy directly to us (but still multicast). Once we receive this, // we will discard our own multicast message Address dest=msg.getDest(); if(dest instanceof PhysicalAddress) { // We can modify the message because it won't get retransmitted. The only time we have a physical address // as dest is when TCPPING sends the initial discovery requests to initial_hosts: this is below UNICAST, // so no retransmission msg.setDest(null); } final boolean multicast=dest == null || dest.isMulticastAddress(); if(loopback && (multicast || dest.equals(msg.getSrc()))) { ..... } you can notice that it will fail if dest == null when doing the equal.
