[jboss-jira] [JBoss JIRA] Updated: (JBAS-3794) Remove all calls to InetAddress.getHostName() (causes reverse DNS lookup)

Remove all calls to InetAddress.getHostName() (causes reverse DNS lookup) ------------------------------------------------------------------------- Key: JBAS-3794 URL: http://jira.jboss.com/jira/browse/JBAS-3794 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: Clustering Affects Versions: JBossAS-4.0.4.GA Environment: Java 5 JBoss 4.0.4 Reporter: Michael Newcomb Assigned To: Brian Stansberry Priority: Minor Fix For: JBossAS-5.0.0.CR1 Any call to InetAddress.getHostName() will cause a reverse DNS lookup. If DNS is not configured properly, can cause slow startup/join times between JBoss clusters. The most notable is in ClusterNode.java: public ClusterNode(IpAddress jgAddress) { if (jgAddress.getAdditionalData() == null) { this.id = jgAddress.getIpAddress().getHostAddress() + ":" + jgAddress.getPort(); } else { this.id = new String(jgAddress.getAdditionalData()); } this.originalJGAddress = jgAddress; StringBuffer sb = new StringBuffer(); java.net.InetAddress jgIPAddr = jgAddress.getIpAddress(); if (jgIPAddr == null) sb.append("<null>"); else { if (jgIPAddr.isMulticastAddress()) sb.append(jgIPAddr.getHostAddress()); else ----->>>> sb.append(getShortName(jgIPAddr.getHostName())); } sb.append(":" + jgAddress.getPort()); this.jgId = sb.toString(); } The following: if (jgIPAddr.isMulticastAddress()) sb.append(jgIPAddr.getHostAddress()); else sb.append(getShortName(jgIPAddr.getHostName())); should be replaced with: sb.append(jgIPAddr.getHostAddress());
