When deploying a simple EAR containing an EJB JAR and a library JAR, exception gets thrown during deployment if path to JBoss directory contains a space character:

Steps to reproduce:
1) Extract jboss-5.0.0.GA.zip to a location containing a space in its path (ex. C:\Program Files)
2) Deploy doNothing.ear
3) Start up the server, deployment will fail with the aforementioned exception

After moving jboss-5.0.0.GA folder to a location that does not contain a space in it's path (ex. C:) deployment completes successfully.
