When i run the following command i get a StringIndexOutOfBoundsException:
mvn -Darguments=" "
Note the space: 'arguments' equal double-quote space double-quote

Here is the stacktrace (with maven 2.0.10 svn r736029):

I'm not sure if it's a bug in cleanArgs method or a bug in the classworlds project... so i report this here.
