[jira] [Commented] (KARAF-1574) When two karaf containers are
started locally, an exception is displayed at startup. A nicer message
would be better.
[ https://issues.apache.org/jira/browse/KARAF-1574?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13429914#comment-13429914 ]
Freeman Fang commented on KARAF-1574:
-------------------------------------
Hi Heath,
It's OK for me basically, I don't think we need the whole original BindException, but if you can indicate which port can't bind, that would be great, something like
It is unable to bind to port xxx...
Thanks for the patch.
