JBoss AS 7.1.1 - HornetQ UnsatisfiedLinkError

You will see this exception when you are running HornetQ in JBoss 7 with debug level log enabled:

FINE [org.hornetq.core.asyncio.impl.AsynchronousFileImpl]  HornetQAIO -> error loading the native library

java.lang.UnsatisfiedLinkError: no HornetQAIO in java.library.path

          at java.lang.ClassLoader.loadLibrary(Unknown Source) 

This however is expected and the log level is trace. This message tries to inform you that the libAIO layer will look for either libHornetQAIO.so, libHornetQAIO32.so or libHornetQAIO64.so on your LD_LIBRARY_PATH. and if it can't use either of those it will fall back to NIO.
