[jboss-jira] [JBoss JIRA] Commented: (JBAS-8407) JBoss AS 6 fails to start with IPv6

Mon Sep 13 13:25:12 EDT 2010

    [ https://jira.jboss.org/browse/JBAS-8407?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12550597#action_12550597 ] 

Richard Achmatowicz commented on JBAS-8407:
-------------------------------------------

There are a few points to note in this log:
(i) SNMP trap emitter is starting with an IPv4 address, despite the fact that an IPv6 bind address was specified. As far as I remember, the SNMP trap emitter implementation was not IPv6 compatible. 
(ii) InvokerLocator is being incorrectly initialised using a malformed URL which results in WARN (and which effectively breaks this functionality, as it probably dow defaults to localhost)
(iii) JMX error, again due to bad URL being specified
