what you can not do is the following:

def loader = this.class.classLoader.rootLoader
loader.addURL("myJar.jar")
def x  = Foo.x // Foo is from myJar.jar

this won't work, because at the point where the jar is added, the 
compiler did already decide that Foo is no class. The script needs a 
recompilation first. So any evaluate that follows will find the class, 
simply because the script therein is compiled after rootloader was used.

I am sure we could find a nice solution if you would give an example of 
the usage of the class, where it currently leads to a 
MissingPropertyException
