If you use MacOSX and JBossAS, then you might have encountered this problem when using the jboss-client.sh tool:
$ bin/jboss-cli.sh
You are disconnected at the moment. Type 'connect' to connect to the server or 'help' for the list of supported commands.
[disconnected /] connect
The controller is not available at localhost:9999
Or you will get this:
$ bin/jboss-cli.sh --connect

It turns out this is bug on the JDK 1.7 that only appears on MacOSX JDK7! To be exact, I have the following: MacOSX 10.7.4 with JDK 1.7.0_05 and JBossAS 7.1.1.Final.
This problem has already been discovered by these posts:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7159361
https://community.jboss.org/message/750861#750861
Except after ready through all, and I can't still get it to work because no one listed a clear steps by steps solution. So I re-summarize it again. You need to use that bug's report workaround solution on both the server and client!
Start the server:
$ bin/standalone.sh -Djava.nio.channels.spi.SelectorProvider=sun.nio.ch.KQueueSelectorProvider
...
18:37:22,555 INFO [org.jboss.as] (Controller Boot Thread) JBAS015874: JBoss AS 7.1.1.Final "Brontes" started in 1686ms - Started 133 of 208 services (74 services are passive or on-demand)
And on separate terminal, run the CLI:
$JAVA_OPTS="-Djava.nio.channels.spi.SelectorProvider=sun.nio.ch.KQueueSelectorProvider" bin/jboss-cli.sh --connect
[standalone@localhost:9999 /]
There, now we may continue to explore the cool JBossAS on the fancy OS.
