When starting JBoss server in standalone configuration we have 100% CPU usage.
There are no deployments.

Please view attached items: thread dump, standalone.conf, standalone.xml.

The JVM version is -bash-4.1$ ./java -version
java version "1.6.0_27"
Java(TM) SE Runtime Environment (build 1.6.0_27-b07)
Java HotSpot(TM) 64-Bit Server VM (build 20.2-b06, mixed mode)
.

Tried also with the latest JVM version (6u33) => high CPU usage.
Tried also with 7.1.1 Final and same configuration(standalone.conf/standalone.xml) => high CPU usage.
