redefining scripted classes

Happy new beanshell year!

In 2.0b-1, attempting to redefine a scripted class throws 
"java.lang.LinkageError: duplicate class definition". Unfortunately the 
"HotSwap" capability in Java 1.4 is only available via the debug API, 
not reflectively. Anyway I believe it currently only works if you don't 
change the set of class member names. In the case that the scripted 
class uses the same members and types as before, couldn't the existing 
loaded class be re-used, as it is just a delegator?

In the general case of arbitrary changes to the scripted class, I 
presume something like the reloadClasses command could be used, 
appending to a chain of class loaders on each redefine.

Am I on the right track here?
