Dear R people,

I have recently started using rJava to interact with Java code that I have
written and am finding it a very useful bridge. Thanks!

I have now run into a problem I can't figure out. If I edit and recompile my
java source code I would like to force rJava to reload the modified java
class.  However even doing:


To restart the jvm doesn't seem to do this.  Is this possible without
restarting R?  Many thanks,
